Soak pitted dates in boiling water.

In a food processor, blend the nut butter, oats, dates, salt and two tablespoons water reserved from soaking dates. If the mixture is too dry, add water one tablespoon at a time (desired texture is chewy).

Add the nuts and mix by hand.

Press the mixture into a six-inch pan.

Melt the chocolate and spread on top.

Refrigerate until chocolate hardens. Cut into bars. Store in the freezer and serve partially defrosted.
