Rhubarb-Hazelnut Frangipan Galettes

This delicious spin on a classic french dessert is an amazing way to use the season's best rhubarb, which is packed with nutrients!  This recipe is nutty, flavorful, sweet-but not too sweet- and smile inducing!  If you would like, you can add strawberries, blueberries or raspberries to the rhubarb to add another dimension.  Galettes can be baked 3 days in advance, simply store tightly wrapped at room temperature. Enjoy!
