Heat olive oil in a large skillet over medium-high heat for one minute. Add ground beef and cook for 8–10 minutes, breaking it apart as it browns, until no pink remains inside.
Sprinkle cumin and chili powder over the cooked beef, stirring constantly for 30 seconds to release the spices' aromas. Add salt and pepper to taste, adjusting seasonings as needed.
While the beef cooks, combine your summer burrito bowl family dinner recipe components in individual serving bowls—divide rice, black beans, corn, lettuce, and bell pepper equally among four bowls.
Top each bowl with the seasoned ground beef, then add diced tomatoes, avocado slices, and shredded cheddar cheese generously. This quick summer dinner family meal becomes customizable at this exact point.
Serve each bowl with one tablespoon sour cream and two tablespoons salsa on the side, allowing everyone to control their own toppings and spice level perfectly.
