This is a salad. A serving with a protein item should be fine for most diabetics. This is not, however, a dessert. I do not recommend eating a bowl full at a time.
1 box (3.4-oz) sugar-free pistachio pudding mix
1/2 cup marshmallows*
1 cup chopped pecans
1 tub (8-oz) frozen whipped sugar-free topping, thawed
In a large bowl combine the drained pineapple with the pistachio pudding mix until well combined. Stir in the thawed whipped topping and blend well. Stir in the pecans then gently fold in the marshmallows. Cover and refrigerate for at least an hour before serving.
Note: This salad can be made day ahead and refrigerated overnight making it great for busy cooks.
*Severe diabetics who have trouble controlling their blood sugar should omit the marshmallows.
