Heat oven to 375 degrees. Grease cookie sheet. In small saucepan, combine dates, sugar, water and nuts. Cook over medium heat for 4 to 6 minutes or until thickened, stirring occasionally. Remove from heat. Cool. Separate dough into 4 rectangles. Firmly press perforations to seal. Place 2 rectangles on prepared cookie sheet; spread each with about 1/3 cup date mixture. Place 2 remaining rectangles over date mixture; do not seal edges. Cut each filled rectangle crosswise into 5 slices; do not separate. Bake for 9 to 13 minutes or until golden.
