Enter a desire for a savory tart, a subsequent google search and the appearance of a "blue cheese tart." I mean really, could the universe have been more specific!
Not wanting to go to the store - this is how my laziness manifests - tomato jam was substituted for the fresh tomato and avocado and we pronounced it delicious! With some homemade ricotta on hand, this came together in a snap, but the extra egg was added due to the dryish nature of the homemade ricotta; most store bought is a little more loose.
I apologize for all of the abundance of sub-recipes. But really, use store bought crust and ricotta to make things easier, I just happen to have them on hand. If you don't have tomato jam - Really??!! You don't have it in your fridge at all times!! (wink wink). I would go with some thinly sliced tomatoes or even some salsa with a sprinkle of sugar and some lemon juice; it helps balance the richness of the tart.
