In a large skillet, heat the olive oil over medium-high heat. Add the sliced flank steak and season with garlic powder, onion powder, chili powder, salt, and pepper. Cook for about 5-7 minutes, or until the steak is browned and cooked to your desired doneness. Remove from heat and set aside.

In a separate saucepan, heat the queso cheese sauce over low heat until warm, stirring occasionally.

In a large bowl, combine the cooked rice, black beans, corn, and diced tomatoes. Mix well to combine all the ingredients.

To assemble the bowls, divide the rice mixture among serving bowls. Top each bowl with the cooked steak, warm queso cheese sauce, diced avocado, and chopped cilantro.

Serve with lime wedges on the side for an extra burst of flavor.
