Put the boxed cake mix into a bowl with 1 cup of ground pecans, add melted butter till a consistency of sand. Pat this into a pizza pan and bake for about 10 minutes, or till browned.
Combine 8 ozs of mascarpone cheese with 4 oz of whole milk ricotta cheese, the zest of one lemon and 1/2 teaspoon of vanilla. (don't use imitation, it's bitter!). Spread this over the cooled crust.
The fruit is up to you, whatever you prefer. Consider grilling peaches and plums....then drizzle some warmed honey over it.
