Do some recipe checking, there are plenty of really good (and of course healthy) that can be prepared pretty quickly. Heck, got a wok? Seriously though, while time is a factor you can work around that. This coming from a guy who will be injecting some chicken breast to grill later today. I am right at home in the kitchen, hell my mom was Italian. I am also blessed with a great wife who enjoys cooking and with us both retired time is never an issue. Also, ask while at the clinic to talk with a dietician about cooking healthy and quick meals. They have tons of literature and free stuff, just ask. Like I said, they were the best people I ever had surround me.
