When I started full timing I bought along the pots and pans from my house. They took up way too much space so I got rid of them and bought a full set of Magma nesting stainless steel, ceramic coated pots and pans. Magma was started by a couple of boaters who saw the need for quality cookware that did not take up a lot of space. This is non-stick cookware that is safe for use with natural gas, propane, electric OR induction heating elements.
I absolutely love this stuff. You can get it from many boating supply companies, Amazon, etc. I got mine from Defender.com
* Magma also makes very good propane grills.
