Marinate the steak in olive oil, garlic powder, salt, and pepper for at least 30 minutes.

Grill the steak over medium-high heat for about 10 minutes, or until desired doneness.

Let the steak rest before slicing it against the grain.

In a bowl, layer cooked rice or quinoa, followed by sliced steak, cherry tomatoes, avocado, cilantro or parsley, and lime wedges.

Serve with sour cream or Greek yogurt and salsa or pico de gallo on the side.
