Lunch recipes for work

Can anyone suggest some good, simple recipes I could make on say the weekend and then take to work each day?

Reheating if needed in a microwave.

I tried searching and most results seem to be about how to reheat in a microwave by adding some water.

Or they show a recipe and it’s all going well but then at the end they say to reheat it by covering it in foil and popping it in the oven.

Not all the useful for work lunches.

Thanks
