  1. Wasn’t quite sure about the flaxseed part of the directions at first, so I just did what I would typically do, which is make flax egg. We roughly doubled this recipe. and it was OUTSTANDING!! My 25-year old son declared it the best veggie burger he has had among those not trying to actually imitate meat!! I think I agree with him!
