Prepare all ingredients. Turn Instant Pot to sauté and brown ground beef for 3 minutes. Add onion and garlic and sauté until cooked through.
Add Italian dressing mix, beef broth, peppers, pepper, Worcestershire, and green chilies if using. Mix.
If using uncooked rice, add rice and water. Add crushed tomatoes and diced tomatoes, without mixing.
Set Instant Pot to "Soup" (or "Manual") "High" for 5 minutes (or 10 if using uncooked rice). Use quick release once cooking is complete.
Add cooked rice (if using instead of uncooked) and parsley to soup. Serve with cracked pepper and garlic bread!
Notes
Store leftovers in the refrigerator for up to four days, or in the freezer for up to 2 months in zip bags. Lay bags flat to freeze, then store upright to save space.
