Have you used Fit N Fresh products? They sell them on Amazon and elsewhere. They have compartments in them to keep wet/dry items separated. A fruit/veggie bowl with a compartment for dips, a breakfast bowl with a spot for milk, cereal and fruit, a salad container with a dressing dispenser, and chilled lunch containers that can have the cold ring removed so the rest can go in the microwave, etc. Nice stuff!
Alas, I still have problems packing a lunch.

I think I'm going to start switching breakfast and lunch, and bring Kashi and almond milk to work. It's soooo easy!
