This is a delectable steak sandwich, which makes a perfect quick supper with some oven baked chips and a green salad. Adjust the seasoning to taste - instead of jalapenos, you could use jarred roasted red peppers for a milder version!
If you have time, freeze the steak (partially or all the way). Then, with your sharpest knife, slice the frozen steak as thinly as you can. That is the hardest part.
When shopping for steak sandwich steak, I advise you pay more attention to the way the meat looks than the cut. You can't go wrong with a nice tender steak, but I tend to look for the cheap steaks with some marbling of fat.
Just so happens, this sammie is the same in northeast MA. I made one yesterday for the first time and a hint would be to get the rawest deli roastbeef and have them shave the meat at .04 on the slicer. I can't get a really good cheesesteak where I live now in AZ, so I got going on my own and it came out great. I carmelized onions, charred a red and yellow pepper. Incorporated the prepared onion/peppers with the pan-fried shaved steak, topped with white american and it was delicious. I will probably expand with pepper rings and different cheeses but this one was great on a sub roll. - 25 Feb 2008 (Review from Allrecipes US | Canada)
This was the easiest steak sandwich to make and my family loved it! I used provolone instead of the sharp Cheddar which gave it a smoky flavor. I will fix this again. - 08 Mar 2007 (Review from Allrecipes US | Canada)
This is the "quintessential" Massachusetts cheese steak! Pop the thing under the broiler for a few mins., if you like toasty bread. Serve with chips, pickle and a coffee shake! - 01 Jul 2006 (Review from Allrecipes US | Canada)
