Ok let me go through some things you might like to look at
http://www.savingdinner.com Healthy Dinner plans, I have the regular, low carb and vegetarian books
http://www.cookingtf.com There is a very inexpensive menu plan service here for people who cook traditionally (nourishing traditions type diet), cook whole foods or need glucose or caesin free meals.
http://www.Menus4moms.com This one has a free dinner menu plan made by a homeschool mom
http://www.recipezaar.com If you go here you can do a search for OAMC and you will find tons of lists of make ahead food to fill your freezer with. Some of my favorites are the mini bagel pizzas, stuffed chicken, meatballs, stuffed shells, smarties (M&M) cookies, perogi lasagna, macaroni and cheese, chicken pot pie, and chicken burritos. In fact I think I might go look up some of those to make for my freezer!

A fun thing you might like to do is get laptop lunch boxes or bentos for your kids. You could fill them the night before and have them ready to go.
You can also set up a crock pot meal in the crock the night before so you just need to pull it out of the fridge and put it in the warmer in the morning.
Lastly one thing that worked for me was to make a simple menu that listed what general kind of food we would eat for each meal everyday. For example
Breakfast-
M-ceral, milk, fruit
T-muffins, milk
W-eggs, toast, juice
T-cereal, milk, juice
F-Oatmeal, fruit
S-pancakes and meat
S-Toast, peanut butter, fruit or juice
Lunch-
M-sandwich, chips, apple
T-soup, crackers
W-sandwich, carrots, apple sauce
T-macaroni and cheese, veggie or fruit
F-sandwich, yogurt, fruit
S-Leftovers
S-out to eat (or whatever, that was just an example)
Dinner-
M-Pasta Meal
T-Chicken
W-Crock Pot
T-Tex Mex or bean meal
F-Homemade pizza or take out
S-Stir Fry
S-a traditional Sunday dinner or casserole
I was a vegetarian for awhile but I can not find the good links I used to have for them. I LOVE the Vegan Dad blog though. He has awesome kid tested recipes on his blog and I think he even put out a cookbook recently.
