Dinner times

For those of you ladies who get off at five or a little later: how do you make dinner on time? Meal prepping? What? I get off at five or six depending on the day and my boyfriend likes to eat dinner earlier (around that time). Usually, by the time I unwind a bit dinner is being served around 7. He is usually playing video games so if I bug him about it too much he'll just say "forget it" all upset. So how can I have dinner ready earlier? Do you have stuff ready in the fridge ahead of time? We don't like to use frozen or microwaveable stuff
