Cheesy steak sandwich

You're going to need:
-left over steak
-diana honey garlic barbecue sauce
-shredded cheese (mozzarella, cheddar, monterey jack were the cheeses I used)
-Sourdough bun or bread
-1/2 medium onion
-margarine or butter
1. Pop your bread into the toaster or broiler to give it a light toasting
2. While that's doing it's thing, cut the onion half into long strips
3. Melt some of your butter in a frying pan, throw the onions in and let them simmer away.
4. Slice your steak into 1/4 inch strips, as many as you want, I guess. I had about 6 strips that were 1.5 inches long. Put in the microwave for abbooouutt 1 and a half minutes.
5. Spread some bbq sauce on the toast, layer half of the steak on the toast, your shredded cheese, and then the other half of your steak. The steak should be hot, so it can melt the cheese.
6. Your onions should be floppy by now, yes, floppy. Throw them on top of the steak, put the other piece of toast or bun on top annnndd..
7. EAT IT!
