Preheat oven to 350 degrees.
Place pretzels in a single layer on a rimmed baking sheet.
Unwrap the Rolo candies and place one Rolo in the center of each pretzel.
Bake the Rolo topped pretzels for 5 minutes.
Remove from oven and gently press one M&M candy into the top of each Rolo.
Allow to cool completely (so chocolate hardens up again) before setting out in bowls.
Multiply the recipe if you need more pretzel bites.
Change the color of M&M candies to fit your specific celebration.
