Pre-heat oven to 350*F.
Spray a muffin pan with oil (or use muffin tin liners). Take a slice of prosciutto and place in each muffin well creating a "cup."
Whisk eggs together with coconut milk, salt and pepper. Pour the egg mixture evenly into the 12 prosciutto cups. Cafefully place a slice of tomato on top of each egg bite so that it sits on top of the egg mixture.
Bake in the oven for approximately 20 minutes, or just until cooked through.
