Prepare the peppers by slicing off the “top” (concave) side of the peppers, leaving the stem. Scoop out the seeds and the membrane.
In a bowl, combine the stuffing and 1/2 cup cheese. Heat in microwave for 1-2 minutes until softened and cheese is melted. Allow to cool for a few minutes.
Spoon the stuffing cheese mixture into the peppers, pressing it into each half. Sprinkle with remaining 1/4 cup cheese.
Arrange the peppers on a baking sheet and bake for around 18 minutes, until peppers are softened and cheese is hot and bubbly.
