01 - Line a 9-inch tart pan with removable bottom using parchment paper for easy removal later.
02 - Pulse almonds and oats in a food processor until finely ground. Add dates, melted coconut oil, and salt. Process until the mixture sticks together when pressed.

05 - Pour the lemon filling over the chilled crust. Smooth the top with a spatula.
06 - Refrigerate for at least 4 hours, or until set and firm.
07 - Garnish with additional lemon zest, coconut flakes, or fresh berries if desired. Slice and serve chilled.
