Chocolate Cereal (I used Chocolate Cheerio's)
Tootsie Roll Midgets (I only used about 10 of these, but sliced each one into about 4 pieces)
Small Pretzel Bites
UPDATE: The ingredient list does not call for one used chocolate cheerio. It calls for any type of chocolate cereal you'd like. I happened to pick Chocolate Cheerio's because that is what I had in the pantry. I measured out 1.5 cups, but you could use more or less. I had a friend say she had to read twice on the Cheerio's and when I went back and looked, I could see how she read one used Chocolate Cheerio. Ha! As I told her, that probably wouldn't be too out of the norm around here, but it wouldn't make the snack mix very chocolatey!
Place all of the above ingredients into a large sealed container and shake. I divided the mixture among several snack-sized zipper bags and now I have a snack already measured out for Ryder in the afternoons. I had a bag this afternoon with him and it was Yum!
