Preheat oven to 375 F. Spray a Silicone Muffin Pan or Silicone Muffin Cups with non-stick spray or olive oil.In the bottom of the muffin cups layer diced meat, if using, sauteed vegetables, if using, cheese and green onions. You want the muffin cups to be about 2/3 full, with just enough room to pour a little egg around the other ingredients.Break eggs into large measuring bowl with pour spout, add Spike, and pepper (if using) and beat well.Pour egg into each muffin cup until it is 3/4 full. I like to stir slightly with a fork.Bake 25-35 minutes until muffins have risen and are slightly browned and set.Egg muffins can be stored in the fridge for at least a week. Reheat in the microwave for less than a minute to warm them.
