Preheat oven to 400°F. Place one sheet of foil on baking sheet. Leave rolls connected; do not break apart or separate. Spread 2 tablespoons vegetable oil spread on bottom of rolls; place buttered side down on foil. Cut entire group of rolls in half horizontally to make 1 large top and 1 large bottom; set top aside. Spread raspberry spread over top side of bottom half of rolls (buttered half)

Arrange ham, turkey, and cheese evenly over raspberry spread. Top with other half of rolls and coat with remaining 2 tablespoons vegetable oil spread. Top sliders with second foil sheet; double-fold all edges to seal pouch. Bake 8 minutes

Turn pouch over; bake 5-6 more minutes or until thoroughly heated. Remove sliders from oven; let stand 2 minutes to cool. Dust top of rolls with powdered sugar. Cut into 12 sliders and serve.
