Turn the Instant Pot to Sauté, add the oil, and let it heat briefly for 30-60 seconds. Once heated, add the beef and minced onion and sauté, breaking up the beef into small pieces as it cooks, until cooked through.
Once the meat browns, add the diced peppers and minced garlic, then sauté for 1 minute longer. Season with a bit of salt and pepper, then hit Cancel to turn off the Instant Pot.
If needed, drain off any excess grease and return the inner pot back to the pressure cooker.
Add the beef broth to the inner pot and scrape up any browned bits of meat from the bottom of the pot.
Season with garlic powder, paprika, onion powder, dried oregano, sugar or honey, and Worcestershire sauce, stirring well to incorporate.
Add the diced tomatoes, tomato sauce, and rinsed rice to the inner pot. Don't stir. Instead, gently push the rice down to ensure it is submerged in the liquid.
Place the lid on the Instant Pot and ensure the vent knob is locked. Set to cook on high pressure for 5 minutes by hitting the Manual or Pressure Cook button and use the +/- buttons to adjust the time to 5.
After the cooking time has elapsed, let the pressure release naturally, or for at least 15 minutes.
Remove the lid, taste, and season with additional salt and pepper if needed. Serve as desired.

Notes
Storage: Leftover Stuffed Pepper Soup can be stored in the refrigerator for up to 4 days or frozen for up to 3 months. Defrost in the refrigerator overnight, add in up to 1 cup of stock and reheat to the desired temp.Peppers: Any color peppers work in this soup. I prefer a mixture of red, yellow, and/or green. But use what you have and what you like!Rice: Be sure to use long-grain white rice to cook in the allotted time. It takes 22 minutes for long-grain brown rice to cook through, and in that time, the peppers will turn to mush--so white rice is best for this recipe. Meat: Use lean ground beef, ground turkey, or ground chicken for this recipe. Sodium: Because the stock, tomatoes, and Worcestershire sauce have added sodium, I wait to add additional salt to the broth until after the soup is prepared--that way I can control the sodium content. Using Frozen Peppers and Onions: Feel free to use a 16-ounce bag of defrosted peppers and onions. I recommend sautéing the mixture with the ground beef for the last few minutes, to give the frozen blend more flavor.Note on Sugar: The sugar/honey is optional, but it does help to balance out the acidity of the Feel free to omit if needed.
