What's in YOUR kids' lunchbox?

I had to post this photo to go along with this blogpost. I saw a little ditty on Good Morning America that talked about these overachieving mothers in Japan that made their kids homemade sushi and fabulously decorated food for their lunch boxes. I guess when you're all packed in like sushi in your house this is FUN? notsomuch.
I don't know about you guys, but my kids are the polar opposites when it comes to lunches. Babyboy LOVES to eat the school lunch. He insists that when I pack, he never has enough to eat. I must say, his school has a lunch buffet that is to be reckoned with. We're talking salad bar, delicious homemade hot protein, super fresh veggies, home cooked desserts, milk, fresh juice. You name it, they've got it. That's what I'm paying the big bucks for, right? He definitely gets more food variety at school than he does at home and I'm 100% cool with that. Love it.
Babygirl on the other hand, is a creature of habit. She does NOT like the idea of a lunch line AT ALL. She wants to know what is going to be on her plate everyday BEFORE it's there. Sooo, here's her daily spread: pre-packaged fresh grapefruit with a stevia pack for sweetener, waffle pretzels with an individual pack of Jif peanut butter, chips with an individual pack of salsa, a bag of mini oreos, 3 biscoff cookies, and a bottle of water. That's it. Everyday. While I'm cool with the nutrition part...she's getting fruit (grapefruit), veggies (salsa) (hush, it's close), protein (peanut butter) and then water, I still feel like she's missing a MAIN DISH. She just refuses to eat a sandwich or a salad and she won't take leftovers from the night before no matter how much she loved them. What to do? How do I mix up the lunch offerings without upturning the apple cart?
