To prepare a tex mex chili meatballs with zesty tomato salsa beans and grains recipe, you will need: 1 pound ground beef 2 tbsp. sour cream 1 cup shredded cheddar cheese 1 1/2 cups diced tomatoes 1/4 cup chopped green onions Instructions Preheat the oven to 375 degrees F. Line 2 large baking sheets with foil. Heat the olive oil over medium-high heat. Add the meat and cook, turning occasionally, until browned on all sides, about 5 minutes. Remove from the heat and set aside to cool. Cut the beef into 1-inch (2.5 cm) chunks. In the bowl of your food processor, add the onion, garlic, chili powder, cumin, salt, and pepper. Pulse until the ingredients are evenly combined. Pour the mixture into the prepared baking dishes. Bake in the preheated oven for 20 to 25 minutes or until meat is no longer pink. Serve warm.
