  1. Turn Instant Pot to saute setting. When display says HOT add in the beef and break it up. Add in the onion. Brown beef for about 5 minutes. Drain off excess grease.
  2. Stir in the garlic salt, pepper, onion powder and italian seasoning. Pour in the broth and scrape bottom of pot so that nothing is sticking. 
  3. Sprinkle in the pasta. Dump in the tomatoes, tomato sauce, tomato paste, sugar, bell pepper and spinach.
