Beef Choices for My cart!

I tried cubes of Bonesless chuck (blacks) call them chunks,tried meatloaf,my customers asked about short ribs.
So I went to the mexican market and they had tons of them, all between 1/8 and 1/4" thick. Tried them on the grill, worked and sold some. Could not charge enuf bvecause the pieces were too small. Went back and asked them t o cut them to my specs. They did, I marinate them in my wife's Teriyaki marinade, grill them and they go like hot cakes. 2 to an order, with homemade(do not use the words)potato salad. $4.00 for the dinner 7.50 Tuerned out to be just what i needed for Beef. NO burgers on this cart.
