Slice the chicken breast into thin, even strips and thinly slice the bell pepper and red onion.
Heat the olive oil in a large non-stick skillet over medium-high heat.
Add the chicken strips to the skillet and season with chili powder, cumin, garlic powder, sea salt, and black pepper.
Sauté the chicken for 5-6 minutes until browned and nearly cooked through.
Toss in the bell peppers and onions, cooking for an additional 3-4 minutes until the vegetables are tender-crisp.
Stir in the lime juice and hot sauce, tossing everything together for 1 minute to create a light glaze.
In a small bowl, stir the Greek yogurt with a tiny pinch of salt until smooth.
Warm the tortillas in a dry pan or microwave for 15 seconds.
Spread the Greek yogurt onto the center of each tortilla, top with the spicy chicken and veggie mixture, and wrap tightly to serve.
