Prep the Peppers. Slice mini peppers in half lengthwise and remove the seeds. Arrange them cut side up on a plate or baking sheet.
Make the Filling. In a bowl, mix cream cheese, shredded cheese, cooked and crumbled bacon, garlic powder, onion powder, salt, and pepper until smooth and creamy.
Fill the Peppers. Spoon the cheese mixture into each pepper half, filling generously but not overflowing.
Garnish & Serve. Sprinkle with fresh parsley or cilantro. Serve chilled as an appetizer or snack.
