I am looking for input on what people eat up on a bigwall. What is light, good and gives alot of energy.

Single serving pre-drained tuna packs. A mixture of bagels (jalepeno, raisen, etc). Canned peaches. Chocolate covered espresso beans. Tortillas+anything. Stuff that doesnt require lots of water to choke down.

Depends on the hike in, as if it's short and easy, it opens up several options for the early day/days. How long you planning on being on the wall?

Hard salami, jerky, and such are great. Cheese for the first day.

My experience is pretty limited here, but last time my partner brought Tasty Bites, and they were oh-so-good. Not too light -- but you've gotta hydrate somehow!

I get a big-ass foot-long sub from a deli, then I add a pound of cold cuts, mustard, and mayo. That and a 4-8 snickers gets me through 3-4 days. After that i'm on to bagels, cheese, mustard, goo, and pepperoni, but then i usually climb in the winter when everything stays frozen and sanitary. In the summer I go for more canned chili and canned fruit salad. If you're cooking, Lipton noodles can't be beat b/c you don't have to drain any water.
I'm usually too busy or tired to eat much. for that reason, its good to keep snacks (trail mix, nuts, granola bars, goo, etc. in you pockets).

energy bar for breakfast, GU all day, salami sandwich for dinner. I'm generally tired enough that I can't taste anything anyway.

If I bring my jetboil I pretty much live off of ramen and oatmeal. Bars n Gu during the day. If no stove then I will pack a big o'l summer sausage and some cheese. throw in some jerkey aswell.
Canned ravioli's if I can spare the weight. Sometimes I have gone just bars, Gu and the summer sausage and usually feel pretty good. There is nothing like a hot Ramen dinner with maybe an added can of green beans after a hard day. The amount of weight of a jet boil and fuel is pretty equal to canned stuff and ramen wieghs nothing. You of course drink all the water you cook with as well so your still taking fluids. Even though salty.
I find bagels to really suck to eat in the mornign especially if it is a cold time of year. Like biting into cardboard.

Nutella and bagels is darn good in the morning. Put both in your sleeping bag at night to warm them up.
Fiber one bars, power shots, m&m's, raisins, tweak (just kidding) makes good lunch.
MRE's (the self heating kind) are delicious, take up little space, are easy to make, warm, contain a fistfull of calories (something like 3000), are light, and require no water. I've found them as cheap as $5 for a five course meal and heater. Didn't include the coffee,though, which is kinda annoying.

I also bring monster energy drinks and extra water. as long as your hauling, you might as well enjoy life.

All you need is vegemite and bagels...

When wanting to pass parties on the wall, little shooter bottles of Jack Daniels woos a party everytime. Quite handy actually.

Lots of canned peaches and pears, great for breakfast and dinner.

Watch out for too much ravioli's as the tomato sauce can burn your mouth if you get dehydrated.

Kid's cheese sticks will last for a while and taste great with a bagel with mustard and relish packs.

Tasty bites are great to eat, but not as much fun the next morning.

If you bring a stove bring brocolli and greenbeans for the first couple days, it helps with the digestion.
