Preheat the oven to 300°F. In a food processor, pulse the nuts together until coarsely ground. Add in the dates, cherries, egg whites, and vanilla until a paste forms. Add in chocolate and give a quick pulse. (Do not over-mix the chocolate so you can taste the big yummy chunks!)

Push the mixture into a parchment-lined 9x13-inch baking dish. Bake for 20-25 minutes until the center feels firm. Remove from the oven, let cool, and cut into bars. Sprinkle a little sea salt over top to enhance the sweetness, if desired.

These will last on the counter for a few days or up to a week or more in the fridge.
