Heat oven to 425°F.
Unroll dough; separate into 8 triangles. Spoon 1/2 tablespoon raspberry jam on wide end of each triangle. Top each with ham and cheese. Carefully fold edges of triangles into center, pinching edges closed and gently forming dough into triangle over filling. Place on ungreased cookie sheet.
Bake 12 to 15 minutes or just until edges are golden brown. Remove from cookie sheet to cooling rack. Cool 1 to 2 minutes. Sprinkle with powdered sugar. Serve immediately.
