Cut 1 lb sweet mini peppers in half lengthwise, leaving the stems on. Scoop out the seeds and membrane.
Dice the onion, and mince the garlic
Line a baking sheet with parchment paper, and preheat the oven to 350 ℉.
Make the filling
Heat 1 tablespoon olive oil in a large skillet. Cook ½ cup diced onion until softened.
Add 2 cloves minced garlic, cook 30 more seconds.
Add 8 ounces hot Italian pork sausage to the skillet and cook, breaking it up as it cooks until browned and cooked through. Remove from heat and cool.
In a large bowl, add the 8 ounces cream cheese softened, the sausage mixture, 1/2 teaspoon black pepper, 2 sliced green onions and half the cheese. Mix well.
Stuff the Peppers
Scoop the filling into the pepper halves, filling them completely (slightly overfilling).
Place on a parchment lined baking sheet, and sprinkle with remaining cheese.
