We can give basic, generic advice with the information you have provided. But to get better recommendations you need to tell us the "mission" you are going on: whether you'll have panniers, a dry bag, or frame bags, how much luggage you want to carry and the number of days and whether you'll be away from resupply spots for long.

Set ups can vary from the ultra spartan, a titanium cup and an alcohol "soda pop" stove, for a few ounces including fuel - ideal for an off road weekend tour - to a full, stacking cookset with room to stuff and MSR Whisperlite type stove inside (see REI's or other backpacking stores for this) which can weigh in at a pound and a half with fuel and can be used for years on end. Also, consider eating utensils, cups, etc.

Personally, what goes on depends on what I am doing. Mostly use 2 stacking pots from REI and a plastic lexan spoon/fork and an MSR Stove. Setup is about a pound not including my Leatherman for food prep.

Tell us more about your "mission"...
