With rum, it sounds like a lite strawberry frozen daiquiri. I haven't tried it yet, but it sounds like a nice occassional treat.
Using 8 medium strawbwerries and 2.5 oz of rum, the nutrition log says this recipe is 220 calories, 0 fat, 10 grams carbohydrate, 2 grams fiber and 90% daily Vitamin C.
The nutrition log says 8.75 oz of red wine is also 220 calories, 0 fat, but it doesn't have the fiber or vitamin C.
