Calling all camping TE women, I need your advice

I've a vacation quickly approaching, and 5 of the 12 days will be spent tent camping and mountain biking/hiking. I won't be moving my campsite during that time so I don't care about things being portable. I do, however, care about taking the right food to fuel my body properly for my activity level, getting enough calories, avoiding food spoilage, and keeping things simple. I dislike eating from cans and won't do it.

This will be my longest camping experience. I've tent camped no more than 2 nights/3 days in the past and had no problem with cold food (large cooler with lots of ice/ice water) and leaving the park for the occasional hot breakfast.

I've a Coleman 2-burner cook stove and am going to see if I can find an appropriate non-Teflon pot or small skillet at Goodwill. However, before I know what cookware I need, I need to figure out what I will cook.

This may seem a silly question, but I've little experience with this. Is it safe to keep fresh/raw chicken on ice/ice water for a couple of days? I wouldn't try to take enough for the entire time, just enough for 2 days then visit the local IGA when needed for more. Is this wise or should I just forget about taking uncooked chicken? I figured I can take some boiled eggs with me, or make some egg-white salad to take.

Trader Joe's has chicken sausages that are quite good, but that's more sodium than I want to have that for dinner 4 nights in a row. I need a significant amount of protein. I can roast veggies and sweet potatoes in foil at the fire (assuming there isn't an open fire ban by then). I don't need to live on energy food and cliff bars for 5 days....though this might be fine for a weekend.

So what do YOU like to cook when camping? I can see taking some pasta, though that isn't something I normally eat. Can one use foil packages to cook on a camp stove? I figure if you can do that on an open fire, then it should be fine on a Coleman stove, unless I am missing something.

I've a tight budget so I need to put a lot of thought into this so I can enjoy my vacation instead of stressing over budget stuff.
