Preheat oven to 450 degrees.
Now make the white bean "chicken". In a large mixing bowl, add the cannellini beans. Now mash with either a potato masher or a fork. Mash all the beans completely.
Now add all the remaining patty ingredients to the bowl. Start stirring to combine. Once it starts to come together, begin to knead with your hands. Knead for a few minutes until it is doughy and no longer sticky.
Now in a separate bowl, combine all the breading ingredients. Stir to combine.
Then, form the white bean mixture into patties. Grab a ball of dough however large you want the "chicken" to be. Then press and flatten out pretty thin so it looks like a chicken breast.
Now place the patty into the bowl full of breading and press breading into the patty on both sides, coating completely. You may need to press down hard into the breading.
Then spray a baking sheet with non stick spray and place the patty on to the baking sheet. Then spray the top of the patty with more non stick spray.
Repeat with all the white bean mixture, then bake for 30 minutes, flipping the patties over halfway through the baking process, spraying the other side with more non stick spray.
After 30 minutes, remove the patties from the oven, top each with as much tomato sauce as you want, spread it around, then top that with vegan Mozzarella.
Bake for another 5-7 minutes, or until the vegan cheese has melted. Serve immediately with pasta or whatever you like. Top with vegan Parmesan as well if it strikes your fancy!
