Puppy chow is great for making ahead. In fact, I'll make 2-3 times this recipe when I make this, and freeze most of it. Then when I have company over, or need a quick snack for the kids, I just take this out of the freezer and serve. You can thaw them on the counter, or just eat them cold. It's also great to make a large batch a few days before a party, so you have one less thing to do on the day of!
