Author Notes
I find the best sandwiches are usually those cobbled together from a variety of delicious leftovers. This is why I find it essential to have on hand the proper accompaniments to make an average sandwich truly great: caramelized onions, good cheese, a variety of herbs and a worthy platform.
Pulling together a sandwich recipe from scratch seems a little silly as I would normally be using last night's grilled steak...but here is a how I might go about it from the beginning.
This could be made with any good, thinly sliced steak, but I liked the sirloin flap for it's quick time in a rub and on the grill. It has a good texture, is relatively inexpensive and marries beautifully with the rich, sweet, caramelized onions. An herbed sauce, ripe tomato, peppery greens, a soft pretzel bun and of course some good, melty gouda perfect this sandwich for me. —savorthis
