It seems to me that if you get Boca or Morningstar crumbles & use a any sausage recipe You will get the flavor of sausage, however it may be too lean. You could use NFDM to help with the moisture. Now this would be fresh sausage, not cured. So Hot Italian sausage, or breakfast sausage would work, I think. We eat a mostly veg diet & I would be interested in what you come up with. As a matter of fact I may give it a try with Morningstar crumbles myself, I use TheSausageMaker's (morning edge) for our breakfast sausage! It seems to have just the right amount of heat for us. I think you would have to stuff it in casings & not make patties, cause I don't think the patties would stay together. But I don't know for sure cause I've never tried it. Sounds like a good project for this winter!!
