Vegan burgers don't generally hold together very well while eating them. Especially since there is no egg, which works well as a binding agent, it can be tough to find or make a good vegan burger that doesn't crumble when you eat it! My black bean burger were a good exception, I had finally found a recipe that makes tasty burgers that don't completely fall apart.
Normally I like to try and make my own vegan burgers but in cases when I can not, I like to eat Yves Garden Vegetable Patties., which are not only delicious but don't fall apart.
Another vegan burger eating solution: eat them in pieces and not in a bread bun. I cut the burger into quarters and enjoyed it with dragon sauce over a salad of greens, red cabbage and carrots on top of steamed jasmine rice.
