Remove the Instant Pot lid and turn on the sauté setting for 20 minutes. (Although you will not use all of this time. I like to have the extra minutes for the time it takes for the sauté to become active.)

In the Instant Pot stainless steel inner pot, add 1 tablespoon of olive oil and garlic and onions.

Sauté for about one minute until the onions are softened.

Add the water, tomato paste, ground beef, and all-purpose seasoning on top of the ground beef.

As the ground meat begins to cook, fold in the all-purpose seasoning and cook until the meat is browned, breaking it up with a spatula as needed.

Sauté in the Instant Pot (with the lid off) until the ground beef is browned.

As the meat browns, continue to fold and stir all the ingredients.

Turn off the Instant Pot and drain the ground beef using a colander.

Set aside the cooked ground beef mixture.

Add the rice, water, and salt to the Instant Pot stainless steel inner pot.

Stir to mix the ingredients and make sure the rice is covered in the liquid.

Close the Instant Pot lid (make sure the valve is in the sealing position – up) and pressure cook on high for 4 minutes.

When the cooking time is finished, allow a natural release of pressure for at least 2 minutes.

To open the Instant Pot lid, move the valve to ‘venting’ and manually release any remaining pressure, if applicable.

Fluff the rice with a fork.

Remove the rice from the Instant Pot and set it aside.

Preheat your oven to bake at 350 degrees F.

Use a sharp knife to slice off the top of each bell pepper horizontally, making sure you have a small amount of the top of the bell pepper sliced off with the stem.

Set the tops aside (do not discard).

Remove all seeds and membranes from the inside of the peppers.

Use a small paring knife to cut holes into the exterior of the peppers to make jack-o-lantern faces. (If your peppers don’t stand upright, use a small paring knife to slice a small amount off the bottom of the pepper to flatten the surface.)

Drizzle each carved pepper with olive oil and rub both the inside and outside to coat.

Sprinkle the salt and pepper mixture on the inside of each oil-coated bell pepper.

Arrange the peppers on a baking sheet or in a casserole dish and pre-bake for about 10 minutes in the Instant Pot Omni Plus oven or 15 minutes in a conventional oven.

While the peppers are baking, combine the drained ground beef, tomatoes, parsley, Italian seasoning, salt, pepper, and the cooked rice, mixing thoroughly.

Set aside the ground beef mixture.

Remove the bell peppers from the oven and use a small spoon to fill them with the ground beef mixture.

Top by sprinkling on the mozzarella shredded cheese.

Place the set-aside bell pepper lids with stems back on top of each pepper.

Place the stuffed peppers back in the oven and bake for 15 minutes in the Instant Pot Omni Plus oven, or 20 minutes in a conventional oven, or until the peppers have softened.

Remove the stuffed peppers from the oven and serve jack-o-lantern stuffed peppers warm, and enjoy!
