Cook your base: Prepare brown rice or quinoa according to package directions. For cauliflower rice, sauté in a little oil with salt and pepper until tender.
Sauté the aromatics: Heat 1 tbsp oil in a large skillet over medium heat.
Add diced onion and bell pepper. Cook 4–5 minutes until softened. Stir in garlic and cook 30 seconds.
Brown the beef: Add ground beef, breaking it up with a spoon.
Cook until no longer pink, about 5–6 minutes. Spoon off excess fat if needed.
Season it well: Sprinkle in chili powder, cumin, smoked paprika, oregano, salt, and pepper. Toast the spices for 30–60 seconds to wake up the flavors.
Make it saucy: Stir in tomato sauce, broth, and tomato paste if using.
Simmer 5–7 minutes, stirring occasionally, until slightly thickened and glossy.
Brighten and balance: Add vinegar or lime juice. Taste and adjust salt, pepper, or heat as needed.
Warm the sides: In a small pan, warm black beans and corn with a pinch of salt. Or microwave in short bursts until hot.
Assemble the bowls: Add a scoop of rice or quinoa.
Top with a generous spoonful of beef mixture, then beans, corn, and greens. Finish with avocado, cheese (if using), a dollop of Greek yogurt, cilantro, and a squeeze of lime.
Serve: Add hot sauce or salsa on top. Enjoy right away while everything is warm and saucy.
