In a blender combine the spinach and milk until liquified. Set aside.
In a large bowl scramble the 12 eggs, mix in green onions, bell peppers, & cheese. Pour in spinach mix (this is what makes it green!)
Pour mix into muffin tins, and bake at 375 degree for 35 minutes. Serve immediately.
The egg bites can be saved for a quick breakfast throughout the week!
