Remove the tempeh from the water and cut into chunks. You can bake the tempeh at 350 for 30 minutes, but I used an air fryer. Spritz the basket of the air fryer with avocado oil, add the chunks of tempeh, set the air fryer at 390 degrees for 12 minutes. Stop the cooking process a few times to shake the basket to move around the tempeh pieces. When done the tempeh should be crunchy on the outside and firm on the inside. Set aside.
