Start cooking the rice according to the package, this usually takes around 20 minutes. Heat a large deep skillet over medium/high heat. Add the ground beef to the skillet. Cook for about 4 minutes, soak up excess grease with paper towels, toss the paper towel. A little leftover grease if fine, it will help thicken/flavor the sauce.
Add the beef burrito seasonings, chili powder, paprika, cumin, salt, pepper, cayenne pepper, onion, garlic powder. Add the tomato paste next, onions, bell peppers and water or broth to the skillet. Cover and simmer on low for about 6-8 minutes on the lowest setting. Make the Jalapeño cilantro sauce while it cooks. If the beef mixture is too runny to your liking you can simmer without the lid on. Using ground meat that's lower in fat will result in thinner consistency.
To make the Jalapeño cilantro sauce add all the ingredients, sour cream, lime juice, cilantro, jalapeños, cumin, salt to a small blender or food processor, blitz well until its mostly smooth.
Assemble the ground beef burrito bowls! Start with a scoop of rice, top with beef/veggie mix, corn, beans, cheese, tomatoes and drizzle a heavy spoonful of Jalapeño cilantro sauce over the top. Enjoy!
