I'm not super keen on bananas. I like spinach or kale, frozen cherries, and some grapes. Green apple, kale, grapes and a kiwi is good too.
I don't have recipes... I usually just scrounge up whatever frozen fruit mix is on sale and add greens (even spring mix is good once blended up) and a few other fixin's (a few almonds, a dash of cinnamon, some hemp hearts, etc).
