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. =P
Now, 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 there were leftovers.
And here's what you need. Lawry's Teriyaki sauce (always available at my local Ralphs) and some crushed pineapple. I used two bottles because of the amount of beef I had, but you can use only one bottle if you have less beef.
Pour the two bottles of sauce, one can of crushed pineapple (half if you're using 1 bottle), and 1 TB minced garlic into a big bowl.
Then begin to prep your beef. I like adding little slits like so. I know some carnivores out there disagree with this method, but this is just my preference.
Then season it liberally with some seasoned salt, lemon salt, garlic salt, regular salt, and pepper. Seems like a lot huh? Trust me, it's not~
Coat each piece of beef thoroughly....
And let it marinate overnight. Make sure to grill it on the BBQ grill because it will taste MUCH better that way. If you want it well done, then just pop it into the oven for about 20 minutes after searing it on both sides on the grill. I don't have a picture of the finished product because we were all too busy eating. =P Enjoy!
