In a small mixing dish, crack the eggs and scramble them with a fork.
Add the milk and some pepper to the eggs.
As the hash browns take on color, turn down the heat to "low"
Mix in the eggs with the hash browns.
Let the eggs cook, but stir the eggs and the hash browns.
Add in the "extras" when appropriate.
Meats: We like ham cubes, but have also used sausage links and BACON!
Veggies: If you are in to that sort of thing, you could throw in some peppers or mushrooms.
Cheese: We like a mild cheddar, but really just about any cheese will do.
Lay out a flour tortilla shell
Spread out some sauce. Mayo works, but you can use Miracle Whip, or Ranch, or Bleu Cheese dressing. Or whatever flavoring you want that compliments the ingrediants you have selected. Heck, Salsa might even be the right flavor!
