Preheat the oven to 350°F (180°C). Line a baking sheet with parchment paper.

Heat a large skillet over medium heat and cook bacon until slightly crispy but still pliable (about 5 minutes). Drain and set aside.

Unroll crescent roll dough and divide into triangles. Split each triangle in half lengthwise to form 32 narrower triangles.

Place about 1 tablespoon of cheese on the bottom of each dough triangle, top with a slice of bacon, and lay a pickle horizontally on the bottom. Roll up and place seam side down on the baking sheet.
