Begin by preparing the rice according to the package instructions, using either white or brown rice.

In a large skillet, heat 1 tablespoon of olive oil over medium-high heat, then add sliced onions.

Add sliced bell peppers to the skillet with the onions and sauté until softened but vibrant.

Push vegetables to the side and add diced chicken breasts, seasoning with garlic powder, cumin, and chili powder. Cook until golden brown.

Layer fluffy rice at the bottom of each bowl and top with the sautéed chicken and vegetables.

Add desired toppings like cheese, Greek yogurt, or avocado to each bowl.
