Sorry about the illness. It can really interrupt what is supposed to be a good thing.
Our leftovers are mostly intentional. For example, Last week I slow-cooked a large roast in the crockpot. As there is only 2 of us it's enough to last the whole week but I froze half of it so it's a fast meal some other time. The rest of it got:
- cut into strips for a salad (I only like salads if they have lots of 'stuff' in them so this is one of many 'stuffs').
- made into a more 'American-style' stirfry (ramen noodles, frozen veggies, meat cut into strips, and sweet chili sauce).
- made into SOS (milk/flour/butter gravy with meat and peas) over a slice of toast. I used half the drippings to make the bulk of the gravy. The rest... Freezer!
The rest of the roast will go into other similar things later.
