Preheat grill to medium heat.
Arrange asparagus on a sheet pan and toss with Challenge Everything Butter Snack Spread. Bundle 3 spears together, then wrap the center tightly with a slice of prosciutto.
Grill 5-7 minutes, gently flipping halfway between, until asparagus is bright green and tender and the prosciutto is crispy. Serve warm or room temperature.
