Hello and welcome to Q and E.
The only other thing I might recommend is investing in a crockpot.
Hamburgers, hot dogs, tacos, and sandwiches are great staples to have in the house of picky eaters. You have a base and each will add to it what they like.
Also try different themes (Mexican night, Asian night, Italian night), my roommates in college loved home made egg rolls since we could change the stuffing as we liked. Also basics are good like veggie sticks, crackers, and you can make dips for either.
Good luck and stay away from the ramen :P
