We've made this for two years now on Thanksgiving, and we'll definitely make it again. It's gluten-free and it's lightened up, which are both nice attributes, but it's also a lovely pumpkin tart by any standards. We really like the crust and topping, and unlike other reviewers, we think that the Greek yogurt's tang provides a nice, subtle counterpoint to the richness and sweetness of the filling and crust. While we do agree that the 2 tablespoons of spice called for in the recipe yields an overly spiced filling (1 tablespoon seems just about right), it really wasn't all that overpowering, and still made for a lovely dessert. Don't listen to all the haters: this tart is well worthwhile, just dial down the spice.
