Vegetarian "Ground Beef"

I love meat: pork, chicken, beef, veal. The list goes on. But I also recognize the value in protein derived from other sources. I have a sister-in-law who's vegetarian, we have friends who are, so it would be nice to have something to offer them when firing-up the grill. The Impossible Whopper at Burger King has great texture compared to other veggie patties, much more akin to a regular burger: not a heavy, mushy ball of bean and binder. I decided to try making something similar by creating a seitan that I could grind and reform into patties. I found that it works great when the ground mix is sauteed as taco meat or "ground beef" for a bolognese.
