Pre-heat oven to 375 degrees F.

Cook your sausage in a frying pan on medium-high heat until its completely cooked through. Drain, then transfer to a dish lined with a paper towel to absorb the excess grease.

Saute spinach in a frying pan with olive oil for a few minutes (it will wilt quickly). Once cooked, drain the spinach and set aside.

In a large bowl, whisk together the eggs and milk until incorporated. Add the sausage, spinach, green onions, salt and pepper and mix together.

Grease a muffin pan with nonstick cooking spray. Carefully fill each muffin cup about 3/4th of the way full with the egg mixture. Bake for 18-20 minutes until fluffy. Once the bites are baked, let them cool for a few minutes. Store in an airtight container for up to a week- I bet you they won't last that long though ;)
