Preheat oven to 425°F.
Add bell peppers, onion and chicken into a bowl. Toss with oil, garlic and spices.
Spread onto a large baking sheet and bake for 15-20 minutes, tossing at the 10-minute mark. You can bump the heat to broil for the last 2-3 minutes to get a little char on everything if desired. I did 18 minutes total – baked for 15 minutes and then 3 minutes on a high broil (500°F).
Top chicken mixture with fresh cilantro and drizzle on lime juice. Toss to combine.
Serve chicken and veggies in warm tortillas with toppings of choice. I recommend guacamole, salsa, cheese and hot sauce.
