First, combine the chopped strawberries and blueberries in a bowl. Drizzle the honey over the top, and mix with a spoon until all of the berries are coated with the honey. Put the bowl in the fridge while you make the crust, this helps the berry juices develop.
To make the crust, start by soaking the dates. Just add the dates to a bowl and let them soak in hot water for 5 minutes.
While they are soaking, add the walnuts, almonds, coconut oil, and sea salt to a food processor. Pulse a few times to chop up the nuts. Next, drain the water from the dates, then add them to the food processor. Pulse it all together for about 30 seconds or so, until the mixture starts to come together, almost like cookie dough. (You may have to scrape down the sides with a rubber spatula halfway through)
Once the dough comes together, take about 2 tbsp of the mixture and roll it into a ball with your hands. Then use your thumb to press in the center and start forming a bowl shape. There should be a well in the center that will end up looking like a mini pie crust.
Repeat with the rest of the dough, and place them on a platter. When you are ready to serve, spoon the berry mixture to fill the pie crusts.
After assembling, keep the mini pies in the fridge to help them preserve their shape until you are ready to serve. Then serve and enjoy!
