Here is a list in my galley of must haves:
Wok, I use this for everything.
Slice and dices hand machine - Plastic with stainless blades ( got it at the state fair)
Great knife set not good or OK but great knife set.
Large wide mouth thermos - I use it for keeping soups, chili and other foods hot during the day and for watches
Peculator coffee pot - I am addicted to coffee
Plastic bread pan that can be used in the oven. I cook not only bread but casseroles in it as well.
Hand chopper for ice and vegetables - Also bought at state fair.
Pressure cooker - Still learning how to use it
Just my short list. For a great book on the Galley I would highly recommend Amanda Neal's - The Essential Galley Companion.
