Brown the Beef: In a large skillet over medium heat, cook the ground beef until fully browned. Drain the grease to keep the soup from being too oily.
1 pound ground beef
Chop the Veggies: Dice the onion, red bell pepper, and green bell pepper while the beef is cooking.
½ cup diced onion, 1 red bell pepper, 1 green bell pepper
Load the Crockpot: Add the browned beef, diced onion, red and green bell peppers, diced tomatoes, tomato sauce, oregano, garlic salt, Worcestershire sauce, black pepper, and beef broth to the crockpot.
1 can, 1 can, 1 teaspoon dried oregano, 1 teaspoon garlic salt, 1 tablespoon Worcestershire sauce, ½ teaspoon black pepper, 3 cups beef broth
Slow Cook the Soup: Stir everything to combine. Cover and cook on low for 6 to 8 hours or on high for 3 to 4 hours, until the peppers are tender and flavors are well blended.
Prepare the Rice: While the soup is cooking, prepare the white rice according to the package instructions so it’s ready by serving time.
2 cups cooked white rice
Serve and Enjoy: Spoon the soup into bowls and top each serving with a scoop of cooked rice—or mix the rice into the pot just before serving if you prefer.
