Core the apples and slice them into 1/4-inch thick wedges.
Arrange the apple slices in a single, slightly overlapping layer on a large serving platter.
Drain the soaked dates and place them into a high-speed blender or food processor.
Add almond butter, vanilla extract, sea salt, and 1/4 cup of the warm water to the blender.
Blend on high speed until the mixture is completely smooth and creamy, adding more water one tablespoon at a time until a thick but pourable caramel consistency is achieved.
Drizzle the date caramel sauce evenly over the prepared apple slices using a spoon or squeeze bottle.
Evenly distribute the sliced almonds, mini chocolate chips, and hemp hearts over the top of the nachos.
Serve immediately to maintain the texture and prevent the apples from oxidizing.
