Preheat the oven to 400°F. Prep a rimmed baking sheet with parchment paper or aluminum foil for easy clean up.
Wash the peppers, then carefully slice the peppers down the middle and, with a sharp paring knife, remove the seeds and ribs. (If you want your poppers really spicy you can leave them in). Do not remove the stem.
Mix the cream cheese, cheddar cheese, parmesan cheese, ranch seasoning mix, green onions and hot sauce in a small bowl. Spoon the mixture into the pepper halves.
Place the bread crumbs in a small bowl or plate, then press the cream cheese side of the peppers into the bread crumbs.
Place the peppers on a baking sheet.
Bake for 12 minutes, then turn the oven to broil and broil 2-3 minutes until the tops are golden brown. Watch them carefully during this phase as they will go from lightly browns to black very quickly.
Serve hot on their own or with ranch dip on the side.
