Step 1: Prepare the Mini Peppers : Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper. Slice each mini bell pepper in half lengthwise, removing seeds and membranes. Drizzle lightly with olive oil, season with salt and pepper, and set aside.
Step 2: Cook the Sausage : In a skillet over medium heat, cook the sausage until browned and crumbly (about 6–8 minutes). Drain excess grease and let cool slightly.
Step 3: Make the Filling ; In a large mixing bowl, combine cooked sausage, cream cheese, mozzarella, cheddar, Parmesan, minced garlic, Italian seasoning, paprika, and herbs. Stir until everything is evenly mixed and creamy.
Step 4: Stuff the Peppers : Using a spoon or piping bag, fill each pepper half generously with the sausage-cheese mixture. Arrange stuffed peppers on the prepared baking sheet.
Step 5: Bake; Bake in the preheated oven for 20–25 minutes, or until the tops are golden and bubbly. Let cool for a few minutes before serving.
