Heat the oil in a large skillet over medium heat and add the onion and bell pepper and cook until beginning to soften and starting to brown, for about 5 to 7 minutes. Add the lean ground beef and cook until no longer pink, for about 6 to 8 minutes.

Step 3

Add the garlic, cumin, chile powder and cook until fragrant, for about 1 minute. Add the tomato sauce, black beans, corn and season with salt and cook for about 3 to 4 minutes.

Step 4

Distribute the cooked rice evenly among bowls and top with the beef mixture. Garnish with avocado, lime wedges, fresh cilantro, radishes, jalapeños and the lime cilantro crema. Enjoy!
