Foods that don't have to be refrigerated/heated?

I'm going to a conference next week and while they asked everyone for dietary preferences, I don't have high hopes based on experience (sure, I'd love another "salad" that's just iceberg with no dressing!), so I'm trying to plan ahead and bring some things with me so I don't starve. Unfortunately, the hotel room doesn't have a microwave, just a mini-mini-fridge and I'm bringing my small kettle, so I mostly have to stick to things that can be stored/eaten at room temp, or prepared with just hot water. So far, I have some soy curl jerky to take to long sessions, a couple of ramen bowls, and some bread and packets of almond butter, but I'm kind of out of ideas. There is a Trader Joe's within walking distance, so I can at least grab some fruit or salad when I get a chance, but is there anything else I'm not thinking of that I should pack and/or plan to buy? The conference is a full week, so I'd prefer not to eat crap (like the ramen) the whole time if I can help it.
