When working in a provisional kitchen, less is definitely more. In a plastic storage bin, set aside the cooking utensils and cookware that you’ll need — those that are compatible with the microwave, toaster oven, etc. Another small bin should keep essentials like aluminum foil, plastic wrap, garbage bags and sandwich bags handy, while everything else goes into storage.
Accept that you will have to wash dishes at some point and determine how you will handle this. Locating the temporary kitchen near a laundry tub or bathroom sink will save valuable time.
