I use a Lodge double dutch oven that is cast iron. It is a combination where the lid is a skillet and the bottom is a 5-quart pot. You can cook everything imaginable in this combination. It is far superior than the nonstick pans that are toxic at high temperature.
Cast-iron cookware is very expensive here, and therefore scarce. If you're cooking in a shopping cart it's unusual for cast iron to be a viable alternative.
