Fresh Pineapple

• Fresh pineapple provides natural sweetness and tropical flavor while containing digestive enzymes that help tenderize the chicken.

• Keep the portion moderate to maintain a diabetic-friendly carbohydrate balance.

Red Bell Pepper

• They’re packed with vitamin C and antioxidants.

Zucchini

• Zucchini absorbs the flavorful sauce while remaining low in calories and carbohydrates.

Carrot

• Carrots provide natural sweetness, fiber, and beautiful color.

Green Onions

Olive Oil

Low-Sodium Soy Sauce

Rice Vinegar

• It brightens the overall flavor profile.
• A small amount goes a long way.

Sesame Oil

How to Make Teriyaki Chicken and Pineapple Foil Packets

• Preheat your oven to 400°F (200°C) while preparing all ingredients so the oven reaches the proper cooking temperature before the foil packets are assembled.
• Wash the bell pepper, zucchini, green onions, and carrot thoroughly under cold running water before drying them with clean kitchen towels.
• Slice the bell pepper into thin strips, cut the zucchini into even ¼-inch rounds, thinly slice the carrot, and chop the green onions into small pieces.
• Trim any excess fat from the chicken breasts and gently pound the thicker portions until both breasts have an even thickness for consistent cooking.
• Pat the chicken completely dry using paper towels to help the seasonings and sauce cling better during baking.
• In a medium mixing bowl, combine the low-sodium soy sauce, rice vinegar, sesame oil, Dijon mustard, grated ginger, minced garlic, monk fruit sweetener, cornstarch, and water.
• Whisk continuously until the sauce becomes smooth, glossy, and fully blended with no visible lumps remaining.

• Taste the sauce and adjust the balance if desired by adding a small splash of rice vinegar for brightness or a pinch more sweetener if the pineapple is particularly tart.
• Drizzle the chicken breasts lightly with olive oil and season both sides evenly with sea salt and freshly ground black pepper.
• Cut two large sheets of heavy-duty aluminum foil, each large enough to completely wrap one chicken breast together with the vegetables.
• Lightly brush the center of each foil sheet with a few drops of olive oil to help prevent sticking during baking.
• Place one seasoned chicken breast in the center of each prepared foil sheet, leaving enough space around the edges to fold and seal the packets securely.
• Divide the sliced zucchini evenly between both packets, arranging the slices around and slightly underneath each chicken breast so they cook evenly in the flavorful juices.
• Add equal portions of the sliced carrots around each piece of chicken, ensuring they are spread into a single layer rather than piled together for more even cooking.
• Arrange the sliced red bell peppers over and around the chicken, creating a colorful layer that will soften while still maintaining a slight bite.
• Scatter the fresh pineapple chunks evenly over each chicken breast, allowing the juices to naturally flavor both the chicken and vegetables during cooking.
• Spoon the prepared diabetic-friendly teriyaki sauce generously over each chicken breast, making sure some of the sauce coats the vegetables as well.

• Use the back of a spoon or a pastry brush to spread the sauce evenly over the top and sides of the chicken for maximum flavor penetration.
• Sprinkle a small amount of chopped green onions over each packet before sealing to infuse additional aroma throughout the cooking process.
• Carefully bring the long sides of the foil together above the chicken and fold them tightly several times to create a secure seal, leaving a little space inside for steam to circulate.

• Fold the shorter ends of the foil inward several times until each packet is completely sealed. Double-check that there are no openings where steam can escape, as the trapped steam is what keeps the chicken exceptionally moist and tender.
• Place both foil packets on a large baking sheet, leaving a little space between them so the hot air can circulate evenly around each packet during baking.
• Transfer the baking sheet to the preheated oven and bake for approximately 25 to 30 minutes, depending on the thickness of the chicken breasts.
• Avoid opening the packets while they are baking. Keeping the packets sealed allows the chicken, vegetables, pineapple, and sauce to cook together in their own flavorful juices.
• About 25 minutes into cooking, carefully remove one packet and use an instant-read thermometer to check the thickest part of the chicken. The internal temperature should read at least 165°F (74°C).
• If additional cooking time is needed, reseal the packet and continue baking for another 3 to 5 minutes before checking again.
• Once fully cooked, remove the baking sheet from the oven and allow the packets to rest for about 5 minutes. This helps the juices redistribute throughout the chicken, making every bite more tender.

• Carefully open each packet away from your face and hands, as a large amount of hot steam will escape immediately.
• Spoon some of the flavorful cooking juices over the chicken and vegetables before serving to maximize moisture and flavor.
• Sprinkle the remaining chopped green onions over the top for a burst of freshness and color.
• Garnish with toasted sesame seeds if desired to add a subtle nutty crunch.
• Serve immediately while hot, either directly in the foil packet for easy cleanup or transfer everything onto a serving plate.
• Pair with cauliflower rice, steamed broccoli, roasted green beans, or another low-carbohydrate side dish for a complete diabetic-friendly meal.
• If preparing for meal prep, allow the packets to cool slightly before transferring the contents into airtight containers for refrigeration.
