Soak walnuts, dates and pumpkin seeds for 4-6 hours. Drain and rinse. Remove date pits. (this is an optional step to make these foods more easily blendable & digestible)
Combine all ingredients, except lemon zest and coconut flakes, in the food processor and process until you have a smooth texture. It’s ok if it’s not perfectly smooth. You may have to stop the machine and scrape the sides with a spatula a couple of times.
Spread coconut and lemon zest mixture on a plate. Taking about a tablespoon of batter at a time, roll little balls between your palms. Then roll in coconut flakes.
Makes 13-14 balls, depending on the size. Keep in the fridge or freezer.
