The patty is featured in the The Impossible Cheeseburger, where it comes served with Red's pickle relish, red onions, pickles, lettuce, tomatoes, mayo, and a choice of cheese. As with the rest of Red Robin's burgers, a side of Bottomless Steak Fries is included.
The Impossible Burger is meant to be a meatless patty that still offers the taste, aroma, and beefiness of a regular hamburger patty.
