Here's my take the stress out of it meal plan, just give each day a theme and then add variations.

(I have a picky 7 & 10 year old)

Monday- Breakfast foods: pancakes, waffles, egg sandwich,ect.
Tuesday- Hotdog or sausage
Wed- Hamburger,sloppy joe or pulled pork sand.
Thurs- Chicken or Pasta
Friday - Stir fry or Tacos
Saturday - Soup or Stew
Sunday - Roast - Chicken or porkloin
Usually I have some leftovers from the weekend and can skip a day cooking during the week.
