Del Taco Restaurants'  (TACO) - Get Report move to embrace burritos filled with plant-based "meat" appears to be going down smoothly with investors.

Shares of Del Taco rose Thursday following the company's announcement it will be adding two new Beyond Meat (BYND) - Get Report burritos to its menu.

Del Taco's stock price edged up a quarter of a percent to $11.47 as the second-largest Mexican quick-service chain in the U.S. reported sales of 2 million Beyond Meat tacos since April.

The new Beyond 8 Layer Burrito and the Epic Beyond Cali Burrito will join Del Taco menu alongside Beyond Tacos and Beyond Avocado Tacos, which the chain first rolled out in April.

"The enthusiasm shown by our fans during the first weeks of our Beyond Meat offerings was undeniable," said John Cappasola, president and CEO of Del Taco. "To that end, we wanted to reward the passion being shown across social media and in our restaurants by utilizing our uniquely seasoned Beyond Meat recipe in two new protein-packed burritos."

In a conference call with investors on May 6, Cappasola credited Del Taco's big leap into the world of plant-based proteins with driving a significant improvement in the company's same-store sales.

Taco Bell is doing research on its own plant-based protein offerings, while Burger King's parent company has struck a deal of its own with Beyond Meat and Impossible Foods.
