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.

The country-wide rollout is expected by years end. Why is the Vegan Whopper showing increased popularity?

...suppliers are trying to tap into increased demand for meat alternatives, especially from younger consumers who often view them as healthier and less damaging to the environment.

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