I used the skillet method of cooking - teensy bit of oil, flip it a few times. Definitely make sure to cook over not too high a flame, otherwise it'll brown before the middle is hot, and that's no fun.
I tried this plain and on a bun with some ketchup. Plain it was a little weird, but the ketchup and bun masked the weirdness nicely. The texture was good - chewy without begin rubbery, tender without being mushy.
But wait, this is supposed to be a cheeseburger. There's cheese in the ingredients list, but no cheese flavor in the burger. That was kind of a letdown. If you're going to call something a cheeseburger, you should be able to taste it.
Texture - nicely chewy but not too chewy
Flavor - not terrible, but better when masked with a bun and toppings
Final grade for this attempt: C
