I'm neither gluten-intolerant nor a strict vegan, but I find that making treats or desserts without flour or dairy is not just an enjoyable and challenging departure from the kind of baking I learned growing up, but it's also deliciously rewarding. These easy chewy little pistachio cookies with dark chocolate chunks are just as tasty as any cookie you could make with flour, eggs or milk, but they don't have any of those ingredients at all. And they're loaded with protein and fiber from nuts, nut butter and sesame seeds, so you can feel good about enjoying them as well.
