Brown the turkey sausage in a skillet with the taco seasoning mixed in.
Dice the green onions and peppers. Place a spoon full of the diced vegetables in the bottom of each greased muffin tin.
Next, layer a spoon of turkey sausage on top.
In a small mixing bowl, mix together the beaten eggs and milk.
Fill each of the muffin tins to the top with the egg mixture.
Top each one with grated cheese and put them back in the oven just until the cheese is melted.
Eat immediately or allow to cool before placing the egg cups in a large resealable bag and freezing.
To reheat, take out as many egg cups as you need. Wrap the egg cup in a paper towel and place it on a plate. Heat in the microwave just until warm.
I find that if you reheat them in the microwave without using paper towel, they get a bit soggy. No one wants soggy eggs, so be sure not to skip this step.
