I've never been a fan of cereal, but I loves me some granola. The problem with granola, once you go gluten-free, is you never really know whether those oats are gluten-free or not. Bob's Red Mill makes a certified GF Rolled Oats, available in an 32-oz bag, which is perfect for making my friend Stacey Graham's easy peasy granola recipe.
I added a bag of GF white chocolate chips, and two cups shredded coconut. This stuff is amazing, and so filling. Toss it in a bowl, add some milk and strawberries, and you'll be stuffed for days.
