Pecan, Oat, and Dark-Chocolate-Chunk Cookies

These hearty treats are like a granola bar and a cookie rolled in one. Homemade pecan flour is simple to make. Grind nuts 1 cup at a time to avoid overprocessing (which will result in pecan butter). This dough is sticky and a bit crumbly (but hey, it's gluten-free and vegan!) -- use damp hands to flatten. Cookies will crisp as they cool.
