Preheat your grill to medium-high heat, around 400°F (200°C).

Generously season the carne asada with salt, pepper, and optional garlic powder or cumin. Grill for 5-7 minutes per side.

Cook rice according to package directions and warm the black beans.

In a bowl, layer rice at the bottom, followed by black beans and corn.

Slice the carne asada and add it on top of the rice and beans, then add tomatoes and avocado.

Mix chopped cilantro, lime juice, salt, and pepper in a small bowl for the sauce.

Drizzle the cilantro lime sauce over the assembled bowl and serve warm.
