Ninja!!! Some good measuring cups, food scale, small tupperware containers, a pill holder that holds a weeks worth of pills with spaces big enough to fit all the ones you'll need, travel mug (if you're like me and take your Protein drink with you to sip on).....I don't have this, but my uncle had the surgery and he pre measured all his meats and stuff and vacuum sealed them so they'd last. So he didn't have to measure anything post-op. I'd personally rather make larger amounts at one time and fill Tupperware's with servings for the week.
Can't think of anything else.
