Montag also shared a photo from the day, tweeting an image of herself and Pratt.

"Thank you @tacobell for the Test Kitchen Throw-Down! Live Más," she wrote.

At the kitchen, Montag and Pratt each created their own unique menu item, with Montag whipping up "The Trifecta."

"This is the best taco ever. It's a triple taco!" Entertainment Tonight reports Montag as saying on the fast food chain's Snapchat. "All the different Dorito flavors with a little bit of nacho cheese, bacon and supreme, who wouldn't want this?"

Ultimately, Pratt's "Pizzarito," a pizza inside a burrito, was crowned the winner.
