This is a recipe I am slowly trying to clone. So far, this is the closest I've come. I'm not so sure Houston's uses an egg white, but I added one to help bind the mixture together. Also, the cheese is optional. Houston's definitely grills their buns in butter, so that's probably another reason why their burgers are so good. If you try this and have any tips for me, please let me know. Thanks!! P.S. Thanks for the reviews. I don't have premium (yet) and can't email you all thank yous, but I'm reading the reviews and appreciate the input.
