These healthy egg muffins are an easy make-ahead breakfast recipe.
Bake 25 to 30 minutes, or until the egg is cooked through. Easy way to check the egg: touch the middle of the muffins... if they are still wet and gooey, they'll need a little more time in the oven. They should feel cooked through.
Serve the egg muffins immediately- with salsa, if desired.
