Teriyaki Steak with Onions, Green Pepper and Pineapple

I had a few NY Strip steaks sitting in a Teriyaki marinade for a few days and I decided to cook them up in my heavy ol' cast iron skillet for a harty lunch and leftovers for a few days. Almost every time I cook a steak there are onions, green peppers, & mushrooms cooked right along side of them to put on top of the steak. Since I had in a teriyaki marinade I decided to do onions, green pepper, and pineapple. But....I did the pineapple separately and I cooked them in some flanders red, my Undead Sour Red to be exact. After I cooked up the steak, onions and green pepper I deglazed the skillet with the beer and then added the pineapple and cooked it until the beer cooked down a bit and thickened up a bit. I then drizzled the sauce over the steak and added the pineapple to the veggies. Oi La.

Use your favorite Teriyaki marinade. Mine is just Orange Juice, Brown Sugar, Soy Sauce, Garlic & Ginger
