Start by heating a large skillet over medium heat. Add the ground beef and cook for about 5 minutes until it starts to brown. Use a wooden spoon to break it apart.
Add the chopped onions, bell peppers, and minced garlic to the skillet. Stir well and cook for another 5 minutes until the vegetables are softened.
Stir in the cumin, smoked paprika, salt, and black pepper. Mix thoroughly to incorporate the spices.
Add the rinsed black beans, cooked rice, and beef broth (or water) to the skillet. Stir until everything is well combined.
Reduce the heat to low, cover the skillet, and simmer for 10-15 minutes. This will let the flavors meld together and ensure the rice absorbs the liquid.
Once cooking is complete, taste and adjust the seasoning if necessary.
Divide the beef mixture into food storage containers, allowing it to cool before sealing and refrigerating.
