They took a while, but were good. I used a small egg and then a bit of aquafaba. I blitzed the oats in the food processsor, took them out and then blitzed the zucchini, carrot and onion, and then everything else. You do have to squeeze the mixture into balls before frying as they do break apart. I would like to try cooking these in the microwave, tell me if you’ve tried that!
