Some frozen strawberries or if you like costco the summer berry blend.
Small handfull of frozen blueberries. (optional)
Vanilla flavored protien powder.
Plain yogurt (flavored is optional, and vanilla works well).
small squeeze of lemon juice or a few tablespoons of frozen oj concentrate.

Forgo the ice, the frozen berries will be more than enough.

If you want it a little sweeter (sometimes the berries are not that sweet) add a few drizzles of raw honey.
