This is a very basic cafe grill steak sandwich. I have what I think of as a very nice marinade I came up with, but I need a sandwich sauce to go with it. I have these crap NY strip steaks that I marinade and grill for a bit of smoke and sear, then I throw them in the blast chiller and then thin slice on about a 25 degree bias. After that I put the meat back in the marinade and when it is ordered I finish off on the flattop. It has a nice carmelizing effect, although it makes a hell of a mess on the flattop. The marinade consists of: olive oil canola blend worcestershire sauce fresh garlic fresh parsley fresh rosemary granulated garlic cumin paprika chili powder salt pepper dried thyme honey(to balance the flavors out) I was topping this with grilled onion, peppers, and and a thick slice of fontina cheese that I steam to melt, then finish off with a sauce of(dont laugh) ranch, sriracha sauce, and A1. I am going to drop the fontina and the peppers for thursday and fryday, but I a bitchin sandwich sauces to top it with... Any ideas?
