this is a good idea thread-
I often use leftover rice- fresh frozen veggies and steam both in the microwave - and then heat some canned beans--(good protein with rice) . I get the beans in tomato sauce only for this purpose. I keep them in stock.
I steam rice and veggies separately and then mix as both require different times.
no beans- you can make a great soup instead.
I will try to bring some other ideas later-
rice beans and frozen veggies are good things to have on hand- you can, of course- make the dish with fresh rice but I freeze l/o rice for this reason-
we often had a free supper once a week just by freezing odds and ends - always different and rather fun- I find left overs only retain their joy if used with in about 10 days.
