The Slider That'll Ruin ALL Other Sandwiches

Описание: If you’ve got leftover brisket, don’t even think about reheating it in the microwave. These Brisket French Dip Sliders are built with melty provolone, buttery toasted buns, rich caramelized onions, and finished with a smoky au jus that’s made right on the pellet grill. We seasoned the brisket with my Prime 4 Ancho & Pasilla Chili Rub to give it that bold, smoky, award-winning flavor.

Smoky. Saucy. Ridiculous. This one’s going on repeat.
