In a large skillet, combine olive oil, chicken, paprika, chili powder, cumin, salt, and pepper. Toss to coat and cook over high heat until seared and cooked through, about 8-10 minutes. Add garlic in the last 2 minutes.
Remove chicken and set aside. In the same skillet, sauté onions until fragrant, about 5 minutes. Add bell peppers, season with salt and pepper, and cook until tender.
Return chicken to the skillet with peppers. Mix well.
For the vinaigrette, combine all ingredients in a jar and season with salt.
Serve the chicken and peppers over rice, topped with lettuce, grilled corn, crumbled cheese, and a drizzle of cilantro lime vinaigrette. Add avocado, jalapeños, and cilantro. Serve with tortillas.
