In a medium mixing bowl whisk 8 eggs and milk. Season with a little salt and pepper and set aside.
Prepare your vegetables by slicing the zucchini and then cut in halves, thinly slicing red bell pepper, and dicing onion.
In a cast iron skillet or enameled cast iron casserole dish heat on medium heat the oil and butter. You can also bake this in a deep dish pie dish. See notes if you are going to fry and bake in a separate dish.
Add all the veggies but the spinach and season with salt and pepper.
Stir fry until the veggies are tender then add spinach and cook another 2-3 minutes. Taste your veggies and make sure they are seasoned to your liking.
Pour over egg mix then add cheese.
Cover and bake for 20 minutes.
Uncover and bake remaining time for 15 minutes or until eggs are done all the way through.
Top with a few sprinkles of paprika or some chopped fresh herbs if you would like.
Serve and enjoy!
