Preheat your oven to 400°F and line a large rimmed sheet pan with parchment paper for easy cleanup.
Cut the chicken breast into bite-sized cubes and slice the bell peppers and red onion into thin strips.
In a small glass bowl, whisk together the honey, coconut aminos, toasted sesame oil, and minced garlic until well combined.
Place the chicken, peppers, and onions onto the prepared sheet pan, then drizzle with the extra virgin olive oil.
Season the mixture with sea salt, black pepper, and red pepper flakes, then pour the honey-garlic sauce over everything.
Toss the ingredients thoroughly with your hands or tongs to ensure every piece is coated in the glaze.
Spread the mixture into a single even layer, ensuring the chicken pieces are not overcrowded.
Roast for 18 to 22 minutes, tossing halfway through, until the chicken is cooked through and the vegetables are tender with charred edges.
