The cooking instructions say to bake them for 20 to 25 minutes, but I usually bake them for less time because my oven tends to burn them. These are pretty delicious and convincing, though. I love to cut them into little pieces and put them on pizza. They're also really good with any sauce: ketchup, sriracha, and Dijon mustard.
I'm also planning on making a vegan "Chicken Parmesan" with these (as soon as I get the time!) They would probably also be super delicious in a wrap with bean sprouts, Italian dressing, and cashew cheese or vegan tzatziki sauce.
