Meal planing is a thankless task, I've often felt the same way. Make your dp come up with one or two ideas.
Roast chicken one day, then the left overs with a jacket spud is one of my can't be arsed to think, 2 days covered, meals. If someone wants a jacket with just cheese and peas, that's fine. If someone else wants it with chicken, salami and jalapeños, salad, that is also fine.
Those pre flavoured while chickens are good. Often not that strong, the breast meat in the piri piri ones aren't spicy. They also tend to come in their own roasting bag, so onto nasty washing up.
We have hot sandwiches a couple of times a week in summer. Turkey or beef steaks, sausages, meatballs, burgers, chicken breast, kebab, roast chicken in some kind of nice bread. Again you can make things as complicated or simple has you like. Someone can have their meat and bread simple or you can go for full on marinating, then every condiment and extra possible.
Last night we had sausages in baguette, those part baked ones. The meal before we had kebabs, which I got marinating in the morning, in homemade pita. Sometimes I'll put the bread maker on to make dough for rolls, or make flat bread but then use supermarket meat balls or burgers. Or I'll get my arse into great and make burgers, use left overs to make mini meatballs for the freezer but then buy bread.
There are days when some kind of breaded chicken and oven chips is the only thing
