Your gonna need two pans.. a small skillet and a large griddle type pan. Place grated cheese on top of slices of bread. Place garlic butter in the bottom of the griddle and put in the bread to het and crisp up(and melt the cheese).

In the small skillet brown the sliced onions for a few seconds.. Dice up the serano peppers and add to pan for about 30 seconds. Add roast beef to pan and squeeze the Lime Juice into tha pan. Do so through a strainer if your worried about seeds ending up in the mix. Add the Inner Beauty Sauce and mix well. Reduce till not "watery". Place roast beef on top of Pumpernickel bread in other pan. Close sandwich w/ the Rye Bread (so that each sandwich has 1 peice of each bread.. This is critical! (Well not really. Hell, you could use Wonder bread for that matter!) Slice sandwiches in half and serve.
