• Grease a 9" tart shell and preheat oven to 350F.
• Place walnuts, sugar and melted butter in a food processor and pulse until all the ingredients have combined.
• Scoop walnut mixture in the tart shell and use your fingers or the back of a spoon to evenly spread the paste into the shell.
• Prick the shell with a fork.
• Bake for 12-15 minutes until the shell is golden. If the shell puffed, use the back of a spoon to press it back as soon as you take it out of the oven. Let cool

Chocolate Ganache Filling

• Place chopped chocolate and butter in a large bowl.
• Pour heavy cream in a saucepan and place over the stove medium heat. Once you notice some bubbles at the edges of the pan, remove from stove and pour cream over chocolate.
• Wait a few minutes before mixing to allow the hot cream to melt the chocolate and butter.
• Use a rubber spatula or a hand whisker to mix the filling until smooth.
• Pour chocolate filling into the walnut shell and spread it evenly.
• Allow to cool and firm for about 30 minutes.
• When ready to serve, sprinkle some melted chocolate or top with fresh fruits.
