Whataburger is bringing back a fan favorite from last summer.

The Sweet & Spicy Bacon Burger is on the menu again starting at 3 p.m. Monday. The burger is made with two beef patties, bacon, grilled onions, Monterey Jack and American cheese. It's all topped off with a special sweet and spicy pepper sauce.

Whataburger spokeswoman Amanda Blease said it's unknown how long the burger will be available.

"This combination of ingredients makes a really unique and great tasting burger, and we're pleased to serve it up again to our fans who have been asking us to bring it back," said Whataburger Vice President of Marketing and Innovation Rich Scheffler.
