Pre-heat oven to 350 degrees.
Prepare muffin tin - spray a 12-cup muffin tin with non-stick cooking spray or use paper or silicone liners.
Prepare filling ingredients: cook and chop sausage, dice ham, shred cheese, chop veggies (green peppers, onions, mushrooms, broccoli, spinach)
Whisk the eggs then add in heavy cream and season with salt and black pepper.
Divide fillings among 12 muffin cups.
Pour egg mixture evenly among the 12 muffin cups. Each muffin cup will be filled about 3/4 of the way full.
Bake - place the muffin tin in the oven for 20-25 minutes or until the egg mixture is set and lightly golden brown on top.
Cool for a few minutes, then serve. Store leftovers in an airtight container in the refrigerator for up to 7 days or follow the instructions for freezing in the post above.
