If using Parmesan instead of nutritional yeast, increase cornstarch by 1 tbsp.
Nutritional estimate is for 4 LARGE slices (this is made in a 9 x 13" pan!) using unsweetened almond milk, linked meat swap (similar to TVP), and no oil to grease pans.
This can be made in advance through the baking stage. Cover and refrigerate, bringing to room temp before baking or baking an additional 10 - 15 minutes.
