Another vote for batch cooking things to have midweek.
I really don't like jar sauce, so won't eat it. But I don't expect DP to have to make sauce from scratch every time he cooks. We both work full time, and I have 2 DDs, so time is precious. Instead, I batch cook a huge pot of tomato based pasta sauce, then freeze it in bags, laid flat. We can then snap off pieces when we need it.
Today we're having a slow cooker meal. I prepped it all yesterday whilst cooking dinner, so today I can just chuck it in and it'll be done for dinner. We also prep things for the air fryer, marinading meat or fish, chopping and seasoning potato wedges, and freeze seperately. Then in the morning, pick and mix one of each, take it out to defrost, air fry later, and add a bag of salad.
I'm not a fan of ready meals, so I do understand that side of things OP, but I also think you both need to makes things easier for yourself when you're both working till late. There's load of recipes online, for batch prep, freezable, slow cooker, or air fryer meals (pinterest is my go to to search for these). Have a look with your DP, and maybe prep together, or take turns. It's fairly easy to get into a cycle of prepping a couple of recipes each weekend, maybe enough for 3-4 meals, to keep a good selection in stock.
