Vicki, I've tried a million of them (and I have a good black bean recipe that I've developed if you want it) but the best non-bean veggie burgers I've made with TVP. If you're not familiar with TVP (textured vegetable protein) you can find it at Whole Foods if you are near one or I've ordered it online. I can't think of the online store I've ordered from but I've heard good things about Dixie Diner You can find recipes on fatfree.com but I usually just use with my old meat-based recipes. The only difference is that you have to re-constitute TVP with boiling water and I usually add a cube or two of veggie bullion for flavor. I'm sure this is way more info than you wanted, but if you have any questions feel free to email me directly.
Quick and easy - TVP (makes just three)

Vicki - My favorite burger is Fantastic's dry mix Nature Burger. It's grain based. Very, very tasty if fried crisp in some oil. Crisp is the secret! I like it on a Kaiser roll with lots of salt and pepper, lettuce, mayo, and b&b pickles. Used as a main dish, it's also good smothered in stewed tomatoes.
