Preheat the oven to 350 degrees F (175 degrees C). Grease a 12-cup non stick muffin tin. Press each roll onto base of muffin cup and press up slightly.
Place green onions and bell peppers into a large mixing bowl. Add eggs, bacon, milk, garlic powder, onion powder, salt, and pepper. Sprinkle Cheddar cheese into the bowl and whisk ingredients together until incorporated.
Pour mixture equally into the prepared muffin cups.
Bake in the preheated oven until a toothpick inserted into the center of a muffin comes out clean, about 25 - 30 minutes. Let cool slightly before serving.
