My favorite Christmas movie is the cartoon Grinch, so by default roast beef is roast beast in December.
This is a really easy way to use up leftover roast beef. Slice it thin!
Roast Beast Sandwich
Ciabatta or baguette
Thinly sliced roast beef
Sautéd bell peppers and jalapeño
Salt and Pepper
Place everything on your bread and wrap in foil. Bake 15-20 minutes in a 350 F oven.
