I also mostly plan for supper, which will then become the next day's lunches and (sometimes) supper too.
I usually do it one week at a time, usually before the big weekend grocery shop. Greens are usually either romaine or whatever greens we picked up at the market (choi sum, bok choi, broc, etc.)
Sunday: Risotto & a bean/bughur casserole + greens
Monday: Repeat + greens
Tues: Pasta & ham + greens
Wed: Char siu + rice + greens...
Thurs: Japanese curry...
