Preheat oven to 375 degrees F. Line baking sheet with parchment paper. Separate biscuits. Roll or pat each piece of dough to 4 1/2-inch diameter.
Place 2 tablespoons cheese in the center of one piece of dough. Top with 1/2 teaspoon pesto and one meatball. Bring dough up around meatball and pinch to seal at top. Loosely tie 100% cotton kitchen string vertically 1 1/2-inch intervals around balls to resemble striations of a pumpkin.
Place on prepared baking sheet; bake 20 to 25 minutes or until golden brown. Cool 5 minutes. Carefully remove kitchen string and place rosemary leaves on top of each roll to resemble a stem. Serve warm.
