Spiral Cut Sausage Banh mi

Preheat grill to medium-high heat. Cut each sausage in half to make four pieces. Carefully push skewer through center of each sausage. Working one at a time, place skewered sausage on cutting board. Make an angled cut around sausage down to skewer, turning as you go. Continue down entire length of sausage; slightly pull on ends to expose spiral cut.
