In a large bowl, mix together the ground beef, rice, egg, cilantro, onions, garlic, cumin, paprika, salt, and pepper. Form the mixture into 1-inch meatballs.
In a large pot, bring the beef broth to a boil. Add the meatballs and reduce the heat to a simmer. Cook for 10 minutes.
Add the tomatoes, carrots, and zucchini to the pot and continue to simmer for an additional 15-20 minutes, or until the vegetables are tender and the meatballs are cooked through.
Stir in the cilantro and season with salt and pepper to taste.
That was simple to make and really tasty. Thank you!
