The last time I made lasagna, I made 5 of them - one we baked and ate that night (and as leftovers over the next few days), and the others we wrapped and froze. This requires you to have several Pyrex baking pans (currently 10-15 US$ each), and substantial freezer space (both of which we already had), but the work required for making 5 pans was perhaps 2x making a single pan, and if we are hungry and don't want to cook we can just take a pan out and bake it, dinner in 30 minutes with no effort. Baked and refrigerated they last several days, enough to eat over several lunches and dinners. Enchiladas also work well for this. Both make a nice alternative to the classic frozen stews, soups, and chilis.
An exercise:
Name something that you do not do but should/wish you did/are told you ought, or that you do less than is normally recommended. (For instance, "exercise" or "eat vegetables".)
Make an exhaustive list of your sufficient conditions for avoiding this thing. (If you suspect that your list may be non-exhaustive, mention that in your comment.)
Precommit that: If someone comes up with a way to do the thing which doesn't have any of your listed problems, you will at least try it. It counts if you come up with this response yourself upon making your list.
(Based on: Is That Your True Rejection?)
Edit to add: Kindly stick to the spirit of the exercise; if you have no advice in line with the exercise, this is not the place to offer it. Do not drift into confrontational or abusive demands that people adjust their restrictions to suit your cached suggestion, and do not offer unsolicited other-optimizing.
