I left out the sugar and used Ezekiel cereal instead of panko. Just gave the cereal a couple of pulses in the bullet. I mashed the beans quite well and used the full 4 tbsp of the BBQ sauce to insure the stickiness. Also I made the mistake of pushing down with the spatula while grilling. DON'T! They are delicate. But THE BEST VEGAN BURGERS I HAVE EVER HAD! Delicious hearty and nutritious! Really hits the burger spot!
