My kids have hot dinner at school and usually want a picnic dinner when they come home. This is usually a combination of sandwhich/wrap, crisps, carrot, cucumber, grapes, melon, ham, cheese, soreen loaf, jelly, yoghurt. They LOVE it. And then I batch cook. So I will make a giant portion of bolognaise. Same some for spaghetti bol, add some kidney beans and spice to some for chilli con carne, mix some with veg and add mash and make a kinda cottage pie.
I also have curry etc made in freezer. I freeze it all then get out what I fancy. We sometimes eat all together, sometimes separate but I always sit with them while they are eating.
Thursday is swimming so that day we have something hot we all like-usually pasta pesto with peas and chicken or pasta meatballs.
