I'm a fan of Spirutein shake mixes (from soy, with spirulina, one of the ultimate superfoods). Although I was reading yesterday about how soy protein isolate (and anything ending in "isolate) is so horrible for you because it's so ultra-processed with bad chemicals (see

Having a shake mixer cup is super helpful -- mine has lines on the side to measure the liquids you're putting in and a whisk-ball thing inside that mixes up the powder while you shake the cup. Mine looks like this:
