Looking for a dessert that will be the perfect ending to a wonderful holiday meal? This gluten-free tart is not only delicious but also guilt-free! Filled with fruit, natural sweeteners and nuts, this is one dessert where you can eat that second helping! Heat oven to 350 F. Using a food processor, combine the nuts and dates and pulse until they create one cohesive mixture. Add in the maple syrup and sea salt and pulse again. Grease a 9-inch tart/pie pan with cooking spray.
