Preheat oven to 200 degrees. Mold wontons into a mini muffin tin. Bake for about 5 minutes, or until the wontons hold a cup shape. Repeat until you have molded about 48 cups. * You can always make more if you need to.
Preheat oven to 350 degrees.
In a medium bowl, remove the sausage from the casing (by lightly squeezing the sausage in the middle, causing the sausage to come out the ends). Add the ranch dressing and mix until well combined.
Add the peppers and cheese and mix to combine. *The filling can be made in advance and stored for up to 2 days in an airtight container in the fridge.
Fill each baked wonton cup with the filling. Bake for 15-20 minutes or until bubbly.
Best served warm.
