If you read any veggie or bean burger recipe, and it has you adding water, you are already on the wrong track. Any time you add water, your burger will fall to pieces or never get done. So, do not saute or make a flex egg. But, do add flex seeds and as many vegetables as you like. A food processor is the only way to go, too. I grind my vegetables, beans, and sometimes my grains (if a small batch) in one. I first put in the veggies, second the beans, and the grains last.
