Preheat oven according to the crescent roll dough package instructions.

Finely dice the white onion, cornichon pickles, and pepperoncini.

In a mixing bowl, combine the cocktail sausages with the prepared vegetables and selected seasonings.

Unroll the crescent dough on a clean surface and cut it into appropriate sizes to wrap your sausages.

Place a sausage in the center of each dough piece, sprinkle a bit of everything bagel seasoning, and roll it up tightly.

Place the rolled sausages seam-side down on a baking sheet lined with parchment paper and lightly spray the tops with oil.

Bake until golden and the dough is cooked through, about 10-15 minutes.

Serve warm with a variety of mustards and a mayo/sweet pickle relish dip on the side.
