Add eggs, spinach and shredded cheese to blender.  Pulse blend for a very short time, just enough to beat the eggs and chop the spinach.  Set aside.

In a skillet, cook chopped sausage in olive oil until crispy, about 10 minutes on medium heat.

Add 3-4 pieces chopped sausage to the bottom of each muffin tray.  Fill 3/4 of the way with egg mixture.

Bake at 350 for 20 min.

Remove from oven and top with sliced white cheddar cheese.
