I don't do either, I cook it and put in plastic containers with Plastic lids. We heat and eat until it is gone, next time I make something else and do the same and on and on. I try to make something on Sundays that hopefully last a week, if not we eat pB sandwiches. I hate the thought of cooking every night, I did that for 25 years when we had kids at home and I didn't work outside the home. Most nights I work on a quilt instead. Much more enjoyable.
