TO MAKE THE CRUST
In the bowl of a food processor fitted with the "S" blade, process macadamia nuts, pecans, vanilla and salt until small and crumbly. Continue processing while adding small amounts of chopped dates until crust sticks together. Press crust into greased (with coconut butter) 9-inch pie pan.
TO MAKE THE FILLING
Blend all the ingredients except the lecithin, coconut butter and lime slices until smooth. Add lecithin and coconut butter, blending until well inncorporated. Pour filling into prepared crust and set in fridge or freezer for about an hour or until firm. Once set, decorate top with lime slices and serve.
