Filet Mignon Marinaded in a Teriyaki/Pineapple Sauce

This is probably the easiest thing you can ever make. It's not really even a recipe because you're going to be using pre-made sauce, but I assure you it will make your taste buds happy. =PNow, obviously if you're not feeding that many people...you do not need THIS much meat. I always go to Costco to purchase filet mignon because it's very economical. =P This was enough to feed 6 adults and
