Preheat oven to 350 degrees. Place 4 pieces of foil on counter and spray with cooking spray. Place tortilla on foil. Place 3 oz ham in the middle of each tortilla, followed by 1/4 cup cheese in each.
Meanwhile, spray a large nonstick skillet with cooking spray. Heat over medium heat and add eggs and egg whites. Cook until eggs are cooked through, scrambling eggs as they cook. Remove from heat and divide eggs among 4 tortillas. Roll up tortillas and wrap in the foil.
Place foil pockets on a baking sheet and bake for 20 minutes. Unwrap and allow to cool to room temperature on a paper towel or kitchen towel. Once cooled, wrap tortillas in plastic wrap or foil, place in airtight bags and freeze.
When ready to eat, remove plastic wrap or foil and wrap in a paper towel. Thaw and warm through in the microwave for 1-2 minutes, or until warmed through, and enjoy! Or, for a more crisp tortilla, thaw then place in a 350 degree oven for 10 minutes, or in a warm skillet to cook both sides until golden. Enjoy!
