1 medium seedless orange
12 oz pkg pitted prunes (see Tip below)
1 1/2 cups raisins
1/4 cup walnuts (optional)
2 Tbsp sugar or granular Splenda (optional)
Cut orange in quarters but do not peel. Use a food processor fitted with the steel blade to prepare the filling. (If you have a smaller processor, you may have to do this in 2 batches.)
Process orange until fine, about 20 seconds. Add remaining ingredients and process 15 to 20 seconds, until fine.
Tip: Feel prunes with your fingertips to make sure they don’t contain pits or you could damage the steel blade.
