Preheat the oven to 350 and line mini muffin tins with mini muffin liners.
In a food processor, chop the nuts of choice (or a mixture) into medium chunks. Put them into a large bowl.
Place ½ of the apples into the food processor and pulse to chop them into small ½ inch pieces then add them to the nuts in the large bowl.
Add the dates to the food processor and chop them into chunks.
Add the remaining large apples chunks, along with the salt, cinnamon and flax to the food processor and process until just blended and the apples & dates are processed, like a chunky apple sauce.
Add these ingredients to the other apples with the nuts in the large bowl along with the raisins and stir well.
Mound the mixture by heaping tablespoon (using a melon-baller is great) into the mini muffin liners, mounding over the top.
Bake for 30 minutes, or until browned and allow them to cool in the tins, to retain shape.
