I have a vitamix from Costco and try to have a green smoothie every day. It's great. Started with baby spinach and a frozen banana, then added an apple. Have tried all kinds of combinations, and pretty much everything tastes good. Try to stick with a basic formula, greens and throw in a couple of sweet things. Banana, cashews, sprouted almonds, fresh coconut, dairy are good for creaminess. Beets and carrots and dates are sweet too as well as all the berries and other sweet fruit. Pretty much stick to spinach, kale but arugula is yummy too, almost anything green I've thrown in has worked, great for alkalinity. Love frozen watermelon chunks in the summer. Raw cacao nubs, cashews, banana, fresh coconut makes an unbelievable delicious healthy chocolate smoothie.
