There's a little secret at Little Miss BBQ, the Phoenix, Arizona eatery that's generated long lines and rave reviews since it began serving pecan- and oak-smoked beef, pork and poultry 10 years ago. 

The not-so-secret is a sandwich called El Jefe, or "The Boss" in Spanish. 

The dish demands devotion from anyone who dares to take on the job of eating it.

The humongous El Jefe comes with a choice of brisket, pulled pork or turkey — paired with, of course, more meat. The second option is sliced smoked housemade sausage, with either mild or jalapeño cheddar. 

The duet of deliciousness is piled onto a Hawaiian-style roll from Phoenix bakery Noble Bread and served with chilled coleslaw, pickles, onions and a choice of one of Little Miss BBQ's signature sauces. 

"It's my personal favorite," Little Miss BBQ co-boss Bekke Holmes told Fox News Digital. "I love the tender meat with the house sausage that gives it that nice crispiness."

She took a deep breath and blurted out, "And then you got the warm meats contrasted by the cold coleslaw and then the crunch of the pickles, and then the sauce on top. It's like all your senses and taste buds get excited at the same time."

"I can say with certainty that when you come here, you will eat southwest BBQ at its best." 

El Jefe is so boss it's not even listed on Little Miss BBQ's online takeout, delivery or catering menus. 

"It's not real obvious we have it," admitted Holmes.

Jalapeño peppers are sprinkled generously throughout the menu, beyond just use as a spicy garnish.

The husband-and-wife team have since opened a second location in the Sunnyslope section of Phoenix.

The smoked meats are spectacular. But added allure comes from the southwestern flair that flavors Carolina-quality pork and Texas-worthy beef.
