Preheat oven to 170 degrees.
Line a baking sheet with parchment paper or aluminum foil.
Place pretzels on the lined baking sheet.
Top each pretzel with an unwrapped Hug candy.
Bake at 170 degrees for 4-8 minutes, until chocolate is just softened but not melted.
Remove baking sheet from oven, and quickly press an M&M candy in the center of each pretzel, on top of the softened hug.
Cool for a few minutes, then chill for about 10 minutes in the freezer, until set (just place the whole baking sheet in the freezer).
Store in an air-tight container or zippered bag.
