Cook the rice: Rinse 1 cup of rice until the water runs clear. Cook according to package directions.
Fluff with a fork and set aside. For extra flavor, add a squeeze of lime and a pinch of salt.
Mix the seasoning: In a small bowl, combine all taco seasoning ingredients. This keeps the flavors balanced and ready to go.
Sauté the vegetables: Heat a large skillet over medium heat.
Add a little olive oil if needed. Sauté the diced onion and bell pepper for 4–5 minutes until softened. Add garlic and cook 30 seconds more.
Transfer to a plate.
Brown the beef: In the same skillet, add the ground beef. Break it up with a spatula and cook until no longer pink, about 5–7 minutes. If there’s excess fat, drain it.
Season the beef: Sprinkle the taco seasoning over the cooked beef.
Add a splash of water (2–3 tablespoons) to help the spices coat evenly. Simmer for 1–2 minutes until fragrant.
Add beans and corn: Stir in the black beans and corn. Cook for 2–3 minutes to warm through.
Taste and adjust salt or heat as needed.
Prep the fresh components: Halve the cherry tomatoes and chop the cilantro. Slice the avocado just before serving, or toss it with lime juice if storing.
Assemble the bowls: Divide rice among 4–5 meal prep containers. Top with the beef mixture.
Add a side section for tomatoes and cilantro. Keep yogurt, salsa, and avocado separate to add after reheating.
Finish with lime: Place a lime wedge in each container for a bright, fresh squeeze right before eating.
Cool, then store: Let everything cool for 15–20 minutes before sealing and refrigerating to avoid condensation.
