What do you cook with? What types of storage containers do you use for food?

Today I picked up a cast iron skillet (have wanted one for years - what took me so long? They are very affordable!), a stainless steel sauce pan and two glass storage containers. I'm really beginning to be very concerned about plastic storage containers and teflon coatings leaching chemicals into my family's food. Since most of our storage containers are plastic and all of our skillets/ frying pans and sauce pans are teflon coated, it may take a while to replace all of it, but that is my goal. What do you use? Any recommendations?
