I'm afraid what I'm going to say next may be me excommunicated as a heretic.
I tried the brisket sandwich at Arby's and I liked it.Yep...Arby's. Fast food place with the big cowboy hat sign.
And yes, I thought it was very tasty. Brisket was tender, with nice smoke and flavor. And while I never think of putting cheese on a brisket sandwich, the gouda cheese melting on top of the brisket added a creamy tang that was really nice. And fried onions are good on anything.
Next time you are grabbing some fast food, give Arby's brisket sandwich a try.
