I just do weekend solo trips mostly, so I like to keep it simple by using the typical prepared hydrated stuff. If all you need to do is boil water, your options are almost limitless. I use this Snowpeak set-up because it’s light, compact, and durable. Plus the pot can be used for coffee. http://www.rei.com/product/787957

If I’m going to be preparing one-pot meals of dried pasta or rice were actual cooking is involved, I like a wider pot with a versatile lid. I have an old MSR Alpine set and just use the smaller pot with lid. It’s not that light, but it’s tough and easy to clean. Plus the lid can be used as a fry pan. http://www.trailspace.com/gear/msr/alpine-2-pot-set/
