Preheat the oven to 375 degrees and line a baking sheet with parchment paper.

Cook the ground sausage in a skillet over medium heat until browned and fully cooked, then drain any excess fat.

Slice each jalapeño in half lengthwise and remove the seeds and membranes.

Fill each jalapeño half with cooked sausage and top with a pinch of shredded cheddar cheese.

Unroll the crescent dough and cut it into thin strips. Wrap the strips around each filled jalapeño half to create a mummy effect, leaving space for the eyes.

Place the wrapped jalapeños on the baking sheet and press two black olive slices onto each one as eyes.

Bake for 12 to 15 minutes until the dough turns golden brown.
