Holiday Preztel Rings (Reindeer Noses)

Spray jelly roll pan with non-stick cooking spray.  Place pretzel rings flat on each sheet.  Unwrap the Hershey's Kisses and place 1 Kiss in the center of each pretzel ring.  Bake at 275 degreees for approximately 3 minutes - just enough to soften chocolate, not to melt it (chocolate should stay in Kiss shape, but readily spread when a single M&M is pushed gently into the center).  Remove from oven.  Place a single M&M in the center of each Kiss, pressing down gently so the softened Kiss spreads and fills the center of the pretzel ring.  If desired, sprinkle warm rings with red and green sugars for additional color.  Refrigerate for 5-10 minutes (or until chocolate is firm), and serve as needed.  Can be stored at room temperature or fridge.
