Great recipe! Since General Mills has now certified Corn Chex gluten free, I use 3 c. rice chex and 3 c. corn chex. We substitute Nature's Path Whole O's for the Corn Flakes to add an oat option. Also, we like nuts, so we use 2 c. mixed nuts instead of 1 c. peanuts and eliminate the crackers. Another option for the crackers is Nut Thins by Blue Diamond, broken into bite-size pieces. Around the holidays, you can find the Chex Party Mix seasoning packets. I am not sure if these are gluten-free, but they appear to be. The packet makes the preparation that much quicker.
