Last year was my first burn. I am, however, a fairly experienced traveler, former Boy Scout and backpacker....
I brought food for the group, who intended to cool elaborate meals....BBQ steaks, some breakfasts, etc.
I brought lots of energy bars, a bit of fresh fruit.
Also, the friend that was "guiding" me to my first burn was an experienced guy. Since we were coming from different places, we me in Reno the might before the final drive out. We ate a very, very nice steak dinner with wine.
We then left for the Burn very early in the morning.
Here's my overall take:
My impression of food is solidly colored by me quickly returning to "bachelor" status; before I was married I sorta ate whatever was quickest. I'm not a picky eater...I'll still eat cold pizza, etc if given the chance. Cold or room temp food does not bother me at all. This may or may not affect you.
By far my favorite stuff was the cooked meals. But, for all their trouble, they really weren't worth it. It was hard to corral everyone for a mealtime. Also, lots of camps offered food when you visit. This shouldn't be your food plan, but I'm saying that you'll likely have lots of little bits of tasty stuff all along.
I brought along pop-tab top cans of vegetables in water. Carrots, beets and corn. I ate these with a spoon and actually tasted pretty good after being left in the sun for about 15 min.
I brought along a sack of the small pop-top stews and such: Dinty Moore, Ravioli, etc. High in sodium I know, but it's only a friggin' week. These to are pretty good just above room temperature sitting in the sun for 15 min. or so.
They also make chicken and tuna in non-refrigerated packs for things like this, and they went over well.
I brought some jerky that I bought in Bishop along the way. This was a big hit in camp. No prep, and really flavorful, even to people that don't normally eat it. Likewise some summer sausage.
It's pretty easy to bring small amounts of fruit or cheese, even milk with you. Just plan on eating these the first few days so you don't have to maintain so much ice. Eat them and be done with them.
All in all I'd say that I spent far too much time worrying about food than I should have. I was never, ever hungry. I brought back a bit of food, and TON of alcohol and mixers back. I will add a bit of variety to the food this time, but plan on going almost exclusively away from fresh food.
I will likely throw a few bones in with friends that are planning big barbecues so that I can partake if I feel like it.
Some people revel in eating well on the playa. For me it feel svery much like when I was in Boot Camp; more of a thing to just get handled expediently. It's not a conscious thing, but just what sort of set in.
