My best suggestion is setting theme nights so you don't have to devote mental energy to this task. I also tend to get faster when I make things repeatedly. Here is what I do. Kids are 4 and 6.
Sunday: double batch of a meal that takes more effort: homemade pasta sauce, chicken and dumplings, soup, fish on the grill, kebabs with rice and salad, enchiladas
Monday: fish - we usually do a sheet pan salmon or cod recipe with roasted veggies

Tuesday: Taco Tuesday - I will make ground beef or turkey and whatever taco shell the kids want. Will generally throw it over a salad for me and DH.
Wednesday: We run around a lot on Wednesday so I usually do pasta or the leftovers from Sunday.
Thursday: Breakfast for dinner
Friday: Take out or make your own pizzas
