Preheat your oven to 400°F and line a baking sheet with parchment paper.
Slice the bell peppers and zucchini into thin strips and toss them with half of the olive oil, sea salt, and black pepper.
Spread the vegetables in a single layer on the baking sheet and roast for 15 to 20 minutes until tender and slightly caramelized.
While the vegetables are roasting, season the chicken breast with garlic powder and the remaining salt and pepper.
Heat the remaining olive oil in a skillet over medium-high heat and cook the chicken for 6 to 7 minutes per side until the internal temperature reaches 165°F.
Remove the chicken from the pan, let it rest for 3 minutes, then slice it into thin strips and drizzle with fresh lime juice.
Warm the tortilla in a dry skillet for 30 seconds per side until pliable.
Layer the roasted vegetables and chicken strips in the center of the tortilla, fold in the sides, and roll tightly to serve.
