Preheat oven to 375 degrees - spray a twelve cup muffin tin with vegetable cooking spray and set aside.In a large bowl, beat the eggs and milk until smooth; add the red pepper, spinach, seasoning, salt and pepper. Stir in half the provolone, and if using, ham.Using an ice cream scoop or ¼ cup measure, scoop the mixture into the muffin tin. Fill 8 to 10 of the cups to about ¼ from the top, then top with a little of the remaining provolone.Bake until the egg is set, the tops are puffed above pan and cheese has turned golden, 12 to 15 minutes.Cool for 2 minutes. Generously top with the Parmesan cheese. Run a butter knife around the outside of each muffin and gently remove from the tin with a large spoon.
