I use all frozen fruit, unless I have a ripe banana that needs used.
1/4 cup Blueberries (or not even that much)
1/2-3/4 cup Tropical Fruit blend from Costco (strawberries, papaya, mango, pineapple)
a few large handfuls of spinach
1/2 cup coconut milk
1/2 cup skim milk
1 tsp or so of frozen apple juice concentrate
blend and enjoy!
A few times a week when I work out really hard and need a protein shake I use:
Protein Powder (chocolate is what I have)
a few handfuls of spinach
sometimes I add a tsp of Peanut Butter
Sometimes some strawberries; depends what kind of mood I'm in.
The great thing I've figured out is that I can freeze my spinach in Ziploc bags and my spinach doesn't go to waste because I haven't used it quick enough. I love this!
