When I'm really paying attention to my diet, I cook twice a week.
Sunday evening I grill a bunch of chicken and steak in the backyard. It's just enough for Sunday night dinner, Monday, Tuesday and Wednesdays lunch. Sometimes I'll just do a huge crockpot of steak and potatoes instead if I don't want to grill. I can't eat cooked food after it sits 3 days. It grosses me out.
Wednesday night, I'll make a big dinner and tuna salad. This covers Thursday and Friday lunch.
I usually go out for dinner and lunch on the weekends. I love to eat out.
OP, if you don't like reheating the rice than use canned vegetables or microwave a sweet potato for your side. It comes out good. Just wrap the fucker in saran wrap then microwave it for a few minutes. Wrapping it traps the moisture and makes it cook less dry.
