I use Optimum Nutrition Vanilla Ice Cream protein powder, lowfat Stoneyfield Farms vanilla yogurt, milk, splash of OJ, 1/2 banana as a base. I mix the fruits up from day to day - I have (all frozen) strawberries, blueberries, raspberries, blackberries, whole dark sweet cherries, peaches, mango, pineapple. I sometimes do the just red, black & blue berries, sometimes just the orange & yellow fruit with more OJ, lately I've been doing strawberry, raspberry, cherry, peach, pineapple, mango. Really good. I do 15-20 g of the yellow & orange fruit, 25-30 g of rasp, blue or blackberries, 50-65g strawberry. I increase some if I leave others out. Never too much pineapple though, it takes over fast.
I've also done banana, lite chocolate syrup, peanut butter or strawberry. Yummy, but you have to be careful with the peanut butter.
