Follow these simple steps to create your delicious Chipotle Chicken Bowls:

1. Cook the Rice/Quinoa: Prepare 2 cups of brown rice or quinoa according to package instructions. Set aside once cooked.

2. Prepare the Chicken: In a large skillet, heat the olive oil over medium heat. Add the diced chicken breast.

3. Season the Chicken: Sprinkle the chipotle chili powder, garlic powder, onion powder, cumin, salt, and pepper over the chicken. Stir to ensure even coating.

4. Cook the Chicken: Cook the chicken for about 10-15 minutes, stirring occasionally, until fully cooked and no longer pink in the centers.

5. Heat Beans and Corn: In a separate pot, warm the black beans and corn over low heat for about 5 minutes. Stir occasionally.

6. Prepare Toppings: While the chicken and beans are cooking, chop the tomatoes, avocado, and lettuce. Set aside.

7. Assemble the Bowls: In each bowl, start by layering a base of rice or quinoa. Top with a generous portion of the chipotle chicken.

8. Add Veggies and Toppings: Layer on the black beans, corn, diced tomatoes, avocado, and shredded lettuce.

9. Finish with Cheese and Sauce: Sprinkle shredded cheese on top, and add salsa or pico de gallo and sour cream or Greek yogurt.
