Have you tried soy products. They have soy sausage thats 50 calories for 2 oz, Its called Gimmee Lean, its in a tube like shape and its in the produce section of most grocery stores. Its pretty good. Also for cheese, there's veggie slices, its low in calories and high in protein, just like the sausage. They also have firm tofu that can be marinated and fried up. YUM, the next day is even better b/c it gets firmer. I would recommend eating it the next day and it takes on the flavors you add to it.
