Add 1 pound ground beef and cook until browned, breaking it apart as it cooks.
Once the beef is browned, cancel the sauté setting and drain any excess grease.
Add ½ chopped onion, 1 diced red bell pepper, 1 diced green bell pepper, 1 can (14 oz.) diced tomatoes, 1 can (14 oz.) tomato sauce, 3 cups beef broth, 1 tsp oregano, 1 tsp garlic salt, 1 Tbsp Worcestershire sauce, and ½ tsp pepper to the Instant Pot. Stir to combine.
Secure the lid and make sure the valve is set to sealing.
Set the Instant Pot to pressure cook for 5 minutes.
Once cooking is complete, perform a quick release.
Stir the soup well before serving.
Spoon into bowls and top each serving with cooked white rice from the prepared 2 cups cooked rice.
Serve warm and enjoy!
