Here is my bare bones kitchen.
Ok, if you can have just one pan, it should be a cast iron skillet. You can fry in this. Sautee'. Broil. Bake. You can use this for your bacon, and your eggs, and for making a mean cornbread, and even for baking ziti or mac and cheese. Quiche. Cake. A frittata. Ridiculously easy to care for. Indispensable.
Good knives are important. If you can only have one, make it a cleaver. It's good for chopping vegetables, as well as for cutting meat, and hacking through chicken cartilage. That nice, wide surface can double for crushing peppercorns, garlic, ginger, etc.
The only other pot/pan I consider essential is a decent saucepan with a lid. Boil eggs, make pasta or rice, morning farina. You can make chili in this, stew, or soup. You can even boil your water for camp coffee or tea. Makes a great mixing bowl in a pinch. The lid not only makes it useful for stewing, but serves as a makeshift strainer.
More versatile than a spoon - a spatula can be used to flip pancakes, slide under eggs, and stir sauces, and even fold merengue, if one has a gentle touch. I like wood better than metal or synthetics. It holds up well to heat, washes well, and feels good in the hand. I'd need this.
So, in my real life, I have a tiny kitchen which is jam-packed with stuff, but I only really NEED these four items to make a kick-ass meal. What areas of your life are jam-packed with gadgetry and novelties, and just STUFF, which are far from essential? Care to join this challenge? Imagine your entire office or wardrobe or living room or WHATEVER were destroyed in a fire, and you had to choose ten items or less to get it going, again, in such a way that you'd feel whole and functional - what would those ten items or less be? Tell me. I'm interested.
