Place ham in food processor, and pulse until finely ground. Mix together ham, green onions, and green peppers. Spoon 1/3 cup of ham mixture and 3 tablespoons shredded cheese onto each tortilla, then roll up. Carefully place filled tortillas, seam side down, in a greased 9x13-inch baking dish.
In a medium bowl, mix together eggs, cream, and milk, flour, garlic powder, and hot pepper sauce. Pour egg mixture over tortillas. Cover, and refrigerate 8 hours to overnight.
The next morning, preheat the oven to 350 degrees F (175 degrees C).
Bake, uncovered, in preheated oven for 50 to 60 minutes, or until set. Sprinkle casserole with remaining 1 cup shredded cheese. Bake about 3 minutes more, or until cheese melts. Let stand a least 10 minutes before serving.
