This could be a Whopper for Vegetarians...literally.

The Impossible Whopper will be available soon at a Burger King near you. The Impossible Whopper as BK dubs it will be made with meat substitutes.

The tryout in St. Louis "went exceedingly well," a Burger King spokesperson told CBS MoneyWatch. The sandwich is set to appear in additional markets in the very near future, the spokesperson added.

A recent Nielsen Homescan survey said 39 percent of Americans were trying to consume more plant-based foods.
