Add the eggs, coconut milk, garlic powder, onion powder, salt and pepper to a large mixing bowl and whisk.
In a separate bowl, mix together the prosciutto, broccoli, mushrooms and bell peppers. Divide the mixture evenly between all 12 wells of the muffin pan, reserving some to put on top.
Pour the egg mixture over top of the meat in veggies, filling each up about 3/4 of the way full.
Top each one with some of the remaining meat and vegetables.
