My neighbor makes these for her bridge club and they disappear in minutes

For a slightly fancier version (my neighbor does this when she really wants to impress her bridge club), brush the tops of the unbaked pockets lightly with melted butter and sprinkle them with a pinch of garlic powder and dried parsley before baking. If you like things extra cheesy, tuck a second half-slice of Swiss inside each pocket or swap in provolone for a milder flavor. To stretch the recipe for a bigger group, cut each baked pocket in half on a slight diagonal so they become more bite-sized, then arrange them tightly on a platter around the au jus bowl. You can also use leftover pot roast or sliced steak instead of deli roast beef—just make sure it’s thin and not too saucy so the dough doesn’t get soggy. For meal prep, assemble the pockets up to a few hours in advance, cover the baking sheet with plastic wrap, and refrigerate; when guests arrive, pull them out, uncover, and bake as directed, adding 1–2 extra minutes if needed. If you need to keep them warm for a while (perfect for game nights or card parties), place the baked pockets on a wire rack set over a baking sheet and keep them in a 200°F oven for up to 30 minutes so they stay crisp instead of steaming and getting soft.
