In a large bowl, toss the chicken strips with olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and black pepper. Let it sit while you prep the veggies.
Heat a large skillet over medium-high heat. Add the chicken and cook for 5-7 minutes, stirring occasionally, until cooked through and lightly browned. Remove from the skillet and set aside.
In the same skillet, add a splash more oil if needed. Toss in the bell peppers and onion. Cook for 5-6 minutes, stirring often, until they’re slightly tender but still crisp.
Divide the rice among 4 meal prep containers. Top each with equal portions of chicken and sautéed veggies. Squeeze fresh lime over the top and sprinkle with cilantro if you like.
