Need menu ideas

Dustin and I would really like to cook at home for all meals except Sunday evening for sure, and maybe even after church on Sunday. We spend way too much money eating out, and really need to focus on eating at home. We never eat at a nice restaurant, almost always fast food, so it would be nice to save enough money that maybe we could occasionally eat at a nice restaurant. The problem is, I am quickly out of ideas on what to cook. My 5 yr old is fairly picky, he will usually try something, even if it is half heartedly. He won't eat veggies, but is pretty good on meat. My 3 1/2 year old is one of the pickiest eaters I have ever seen. It is a battle, and I mean battle to get him to try anything. My 2 yr old will eat anything in sight. He is the least picky child I have ever seen. lol He will eat plain lettuce, doesn't care if there is dressing or not, will eat any type of soup or stew. Dustin is fairly picky as well. He won't go near a salad or most veggies. I also would like to spend as little as possible per meal, the reason for eating at home is to save money. With both of us working we aren't home until after 4:30 and we like to eat shortly after 5 if Dustin is home. So it can't be anything that takes a long time, unless it is something I can start over lunch break at 12:30 and then leave it when I go back to work. So what are your wonderful meals? I have been searching for recipes, but most include weird sauces or tons of veggies that my family wouldn't eat. If you cook all the time at home how do you do it, a week, month? Do you set a schedule or just cook what sounds good to you at the moment? How far is your schedule out? HELP! lol
