Put the onion through nutritional yeast (or herbs if using) in a food processor and pulse until the onion is chopped up and the seeds are broken up. Add the black beans and wild rice and process until it comes together but not too long. Add that mixture to a bowl and add Bragg amino and millet. Stir.
To form the burgers, I used a Mason jar lid with plastic wrap and put 1/2 cup of the burger mixture pack it down. I put the burgers on a plate and then transferred them to the parchment-lined CrispLid basket which was on the high trivet.
I cooked them at 400 degrees for 8 minutes, then turned them carefully and did another 8 minutes on the other side.
