Preheat your oven to 375ºF.
Separate the crescent rolls into 8 triangles.
Pour the spaghetti sauce into a bowl or saucepan.
On each crescent roll triangle, place one half slice of mozzarella cheese.
Dunk one of the strong>chicken fingers into the spaghetti sauce, ensuring it's well-coated, and then place it on top of the cheese.
Roll up the crescent dough from the wider end to the tip.
Place each rolled crescent on a cookie sheet.
Sprinkle each roll with garlic powder.
Bake for about 15 minutes, until golden.
Remove from the oven, top each crescent with remaining mozzarella cheese, and bake for an additional 5-8 minutes.
