Found a smoothy recipe that's pretty good. All I had was grapefruit juice which makes a smoothy a little tart and even bitter, so a different juice would be better- like mango. Add banana, a flavored yogurt, blueberries or other fruit if you have it- I didn't but I used rasberrie yogurt, ice. Blend till ice is crushed. Add cinnamon and nutmeg- mmmm good.
