1 (10 oz.) package frozen chopped spinach, thawed and well-drained
7 eggs or 1 3/4 c. egg substitute
3/4 c. shredded cheddar cheese
1/4 c. finely diced red bell pepper
1/4 c. finely diced mushrooms
1/4 c. finely diced onion
Line 12 muffin cups with foil baking cups; spray with non-stick cooking spray.
Combine all ingredients in a bowl and mix well.
Divide the mixture evenly between the muffin cups. Bake at 350 degrees for 20-25 minutes, until set and a knife inserted in the center comes out clean.
Store refrigerated. Remove from foil liners and reheat in the microwave when you're ready to eat them.
