This is a fun, easy recipe and it's very addictive. It's fun to change the colors of the M&M's with the holidays! I got this recipe from a friend of mine and I believe that she got it out of Taste of Home magazine possibly?? The quantity that you'll get will depend on the number of pretzels that are in the particular bag that you're buying. Be sure to allow for broken pretzels in the bag as that's just inevitable. I have only been able to find the "square" pretzels at Walmart.
