Robin, when I was in the hospital for months in Atlanta, getting one surgery after another to rebuild my leg in 2000-2001(9 total operations), I hired a young chef from Whole Foods. He would bring me a couple days worth of meals 2-3x a week, mostly salmon & greens & root veggies (it was fall/winter). I had coolers in my room, jugs of spring water, supplements for bone growth & immunity, almonds soaking/sprouting in the window sill. Doctors, nurses and interns would come in, & some would wig out. Others thought it was great. I recovered in record time & my primary surgeon made a special late night trip after his Thanksgiving dinner with his family to bring me organic turkey (he's from Cali, San Diego, in fact he lives there now).
That shitty hospital food will kill ya if the free floating germs & viruses in the hospital air doesn't do ya in first... Your dad has you when he's at home, ie you're his personal chef & #1 advocate.
My parents were pretty useless, as they couldn't grok what I did and didn't want in a typical meal delivery, much less a week's worth of full on menus, lol. So I had to improvise for myself from my hospital bed, armed with an Atlanta phone book & a lot of time on my hands.
Might healthy, organic food delivery be apropo for him too?
