Preheat the oven to 450°. Set out a 9-10 inch nonstick oven-safe skillet.
Set the skillet on the stovetop over medium heat. Add the butter. Once melted, add in the diced red pepper and green onions. Salt and pepper liberally. (This is the only time salt is added, other than cheese.) Sauté and stir for 3 minutes. Then stir in the spinach and continue to sauté until the spinach wilts down.
Meanwhile, measure the egg whites into a large glass measuring cup/pitcher. Add in the Italian seasoning and garlic powder. Whisk until extremely frothy.
Once the spinach has wilted down, pour the egg white mixture into the skillet. Use a rubber spatula to push the egg whites around the bottom of the pan until they are mostly cooked through and just the top layer is liquid, about 5 minutes.
Then sprinkle the feta cheese and shredded pepper jack cheese over the top of the frittata and place in the oven. Bake for 5 to 10 minutes until puffy and cooked through in the middle.
Shake the skillet a little to loosen the sides. Then slide out of the pan onto a cutting board. Cut into six wedges and serve warm.
