How do I get a good friend to try a yummy, yummy vegetarian hamburger?!

I would bet $100 that your friend could smell the "veggie" from 10 feet away.

I'm a vegetarian, and I've tried a few brands. The Boca burgers are tolerable... ish...

You can always try vegetarian hot dogs. Apparently it's easier to fake the taste of horse lips and salt.

Encourage him to expand his horizons, broaden his palate, yadda, yadda.

Amy's Texas Burger is probably the best. And ketchup and mustard hide a multitude of sins.

Don;t tell him it is vegetarian, when he is smacking his lips, tell him

Everything is better with soy bacon.

YUMMY!

tell him you made burgers then after he eats it tell him it was veggie.
