Step 1: Prepare the Rice : Rinse the rice under cold water until the water runs clear. In a medium saucepan, combine rice, water, olive oil, and salt. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes. Remove from heat and let sit covered for 5 minutes. Fluff with a fork, then stir in lime juice, zest, and cilantro.
Step 2: Cook the Ground Beef : Heat olive oil in a skillet over medium heat. Add onions and cook until soft, about 3 minutes. Add garlic and cook briefly until fragrant. Add ground beef and cook, breaking it up with a spatula, until browned. Drain excess fat if needed. Stir in spices, tomato paste, and beef broth. Let simmer for 5–7 minutes until thick and well-seasoned.
Step 3: Prepare the Toppings : While the beef cooks, warm the black beans and corn in separate small pans or the microwave. Dice the avocado, halve the cherry tomatoes, and chop the red onion and cilantro.
Step 4: Assemble the Burrito Bowls : Spoon cilantro lime rice into each bowl. Top with seasoned ground beef, black beans, corn, avocado, tomatoes, onion, cheese, and salsa. Garnish with fresh cilantro and lime wedges.
Step 5: Serve : Serve warm, allowing everyone to customize their toppings as desired.
