Try the Moosewood Restaurants cookbooks. The low-fat cookbook is great and has lots of easy recipes that use common kitchen ingredients (you don't have to go out and buy all kind of stuff you've never heard of before.)
Also, try beans - black beans, garbanzo beans, pinto beans are all good and work really well in most salads. Beans are high in protein and fiber, so they keep you full without lots of fat.
Quorn brand makes some really yummy chicken substitutes. You can usually find Quorn at co-ops or Whole Foods. The chick'n cutlets with gruyere (sp?) are to die for! Yum. Morningstar makes really yummy breakfast "sausages" and buffalo "wings" if you're craving meat-y things without the meat.
Good luck!
