How to Make a Difference

How to prepare the bell peppers

Cut off the stemmed tops to prepare bell peppers. Then, scoop out the seeds and ribs and discard them. To make smaller portions, you could also cut the peppers in half.

Before stuffing, the peppers must be briefly cooked to ensure they are tender enough to pierce easily with a fork. This step can be done quickly in a microwave. Place the peppers flat-side down in a microwave-safe dish. Microwave for 5-6 min.

Pre-bake the peppers cut side down in a 425 degree F oven for 30 minutes if you don’t have a microwave. You can grill the peppers by pre-grilling them on an oil-coated grill for 6 to 7 minutes.

Although you can stuff bell peppers, they will still retain their crunch texture.

Bake covered with foil in a preheated oven at 425°F for 30-40 mins or grill at indirect heat at 350°F for 30-40 mins, or until bell peppers are tender and cheese is melted. Enjoy! Garnish with fresh basil

Bell pepper preparation

Each bell pepper should be cut in half. To make smaller portions, you can also cut the peppers in half lengthwise. By scooping out seeds and ribs, hollow the bell peppers. The seeds and ribs can be thrown away. You can save the tops to use in other dishes. For the fastest cooking, pre-cook peppers in a microwave. Place the peppers cut-side down in a microwave-safe, deep dish. The bottom of the container should be filled with about 1/2 inch of water. Microwave the container for between 5-6 minutes. You may need to adjust the cook time for your final dish by using other pre-cook methods such as baking, blanching, and grilling. For blanching, boil the peppers for two minutes in a saucepan. Then place them in an ice bath. Place cut side down in a casserole dish. Cover the bottom with water. Top with foil. Bake for 20 minutes at 425F. Place the cut-side down on oiled grates and cook for about 6-7 minutes. Flip halfway through.

The filling

Preheat oven to 425 F if baking. Grilling: Prepare grill. Over medium heat, brown ground beef and then break it up into smaller pieces. Cook the onion in the skillet until it is soft. Stir in garlic, and cook for about one minute. Mix in tomato paste, Italian seasonings, peppers, salt and water. Bring the mixture to boil. Once it has boiled, reduce heat to low and simmer for about 10 minutes. Allow the mixture to cool in the pan. Stir in the cauliflower rice. Once the mixture is cool, add cheese cubes to it and mix well. Fill the bell pepper shells about 1/4 cup with the meat-and-cheese mixture. For baking, place the peppers cut side up in a casserole or cast iron pan. Place the casserole dish in a foil-covered oven safe. Bake at 425F for 30-40 minutes or until peppers are tender. Grill the peppers on a cast-iron pan. Place it on indirect heat. Cook for about 30-40 minutes.
