Books I have seen in new and used bookstores:

Bachelors Aid Cookbook, Owens
The Campus Survival Cookbook, Wood & Gilchrist
College Student's Cookbook, Lambert
Cookbook for One, O'Neill
Cookery for One or Two, Swain
Eating In, Official Single Man's Cookbook, Lippman & Malonado
Meals for Two, Culinary Arts Institute
Rice Bowl Recipes, Asada
Single Servings, Bell
Starving Students Cookbook, Hall

Those should give you a start. Especially the College Student type books.
Another source of ideas would be Camping Cookbooks. There are quite a few
aimed at the single camper. A few that come to mind a

Cooking the One Burner Way, Gray/Tilton
The One Burner Gourmet, Barker
The One Pan Gourmet, Jacobson
Simple Foods for the Pack, Sierra Club

Even more esoteric are cookbooks aimed at the single touring bicyclist,
don't have the names for those.

Hope this is of some help....I probably just scratched the service. But a
good perusing of book stores (especially the used ones) will get you
started....Eric
