I don’t know anyone that likes dealing with mid week dinners - it’s dull and it never ends.
Since you don’t, you are near full time with a toddler, your Dh needs to step up here, and your 13 year old can do one night a week (kids cook Fridays, it’s a thing)
Can you avoid some cook meals so you can drop anyone cooking say twice a week?
Can you pre-prep some meals eg veggie and not veggie chilli and then everyone has rice and salad with it? Cook in a batch so you have 4 servings of each
If you do 2 days, Dh does 2 days, DD one day and pre-prepped 2 days then that’s easier.
You get them to agree on 4 meals they will both eat for your cook days - he can deal with macaroni cheese I am sure, and she can have a veggie sausage when he’s having pork.
On the nights he is cooking, she fends for herself out of freezer (in which there will be preprepped chilli or whatever) if she doesn’t want it. Same for him the night she cooks.
You will probably have to take on teaching her cooking - start with pasta or something like that.
Think up some easy ideas, call a family meeting with the pair of them, and stick up a rota and a shopping list to add things to.
