Mexican "Fudge" makes a great appetizer. It goes together quickly, is easy to serve, and is delicious. Also, this recipe is easy to modify: just think of all the ingredients that you could add to the egg mixture--a variety of finely minced sautéed vegetables, olives, refried beans, . . . Or substitute for the taco sauce: a little honey-mustard dressing or some sweet-sour sauce.
