1) Preheat oven to 350 degrees F. Chop vegetables.
2) In a large bowl, whisk together the remaining ingredients. Add spinach or other diced vegetables and mix.
3) Use nonstick spray to grease the muffin or mini-muffin pans. Fill muffin pans 3/4 full of mixture and bake at 350 degrees F. until set in the middle and firm (about 20 minutes if egg and vegetable mixture is split into 12 muffins).
