Pull out 2-3 good looking strawberries and put aside for topping.
Soak 5 pitted dates in warm water. These will be used for the filling. If dates are relatively soft, soak in warm water for 10 minutes. If dates are dry to begin with, they may need to soak for up to 30 minutes to soften.
MAKE THE CRUST: place pecans in food processor and grind until they are a coarse meal. Then add the dates and continue to process until thoroughly combined. Press the mixture into the bottom and up the sides of a pie plate to form crust.
Arrange 4 cups of the sliced strawberries on top of crust and set aside.
MAKE THE SAUCE: drain dates that have been soaking and place in food processor along with the remaining 1 cup sliced strawberries and lemon juice. Puree until smooth.
Pour sauce over strawberries in pie plate.
Use the 2 strawberries that were put aside to decorate top of pie.
Refrigerate for a minimum of 1 hour or overnight to set pie*
Notes
DATES: Buy medjool dates with the pits still in and remove them yourself. They will be fresher and generally more moist. If your dates are already pitted, you may need o soften them. Soak in warm water for at least 30 minutes and then drain well before continuing. ¾ cup dates is equivalent to 10 large or 14 medium dates. TIMING AND MAKE AHEAD: This pie is best served a couple of hours after preparing, but will hold up fine in the fridge overnight as long as it is tightly wrapped. If you must make this pie in advance, make each part and store separately, then assemble closer to time of need. The crust can be made and rolled into a round ball and tightly covered with plastic wrap 2-3 days in advance. The sauce can be made and stored in a glass jar up to 5 days in advance. Strawberries should be sliced same day if possible or up to one day in advance and stored in a covered container in the fridge.
