💗 Photo 1: Prepare bell peppers and roast them. I prefer to pre-roast my peppers so the filling doesn’t have to stay in the oven too long and so the peppers are medium-soft in the final dish. Feel free to play around with the roast time at this step if you prefer firmer or softer stuffed peppers.

💗 Photo 2: Sauté garlic and onion in olive oil until fragrant, then add the cauliflower rice. Cook until any extra moisture evaporates so you don’t end up with a soggy filling.

💗 Photo 3: Add ground beef, salt, pepper, and Italian seasoning. Sauté until the beef is browned.

💗 Photo 4: Remove skillet from heat. Stir in tomato sauce and half of the mozzarella cheese.

💗 Photo 5: Fill peppers, sprinkle remaining cheese on top, and roast.

For an extra-gooey melted cheese appearance, hand-shred the Mozzarella cheese instead of using pre-shredded cheese, which contains anti-caking agents that hinder melting. (I used pre-shredded for these photos, as you can see!)

💗 Photo 6: Serve and enjoy!

Fun fact: Did you know that bell peppers are actually more nutritious cooked than raw? The carotenoids and Vitamin C in bell peppers become more bioavailable as the cooking process breaks down the cell walls.
