What happens when Vietnam's iconic bánh mì sandwich collides with America's iconic burger?

The Lucky Bun.

That's what Tucson musician Nancy Bright is calling the signature sandwich at Lucky Girl Café, her hitch-along mobile kitchen that quietly debuts today.

Bright plans to introduce Lucky Girl at today's Tucson Food Truck Roundup from 5 to 8 p.m. at Emmanuel Baptist Church, 1825 N. Alvernon Way.

Bright, half of Tucson's popular Bright and Childers acoustic duo, said Lucky Buns were inspired by her daughter-in-law, Mary Nguyen-Hodges.

The sandwiches are made with torta rolls instead of the French rolls in the bánh mì. Burgers - beef, turkey or vegetarian - are seasoned with an Asian-infused marinade and Vietnamese spices before being charbroiled. The sandwiches are dressed with lightly pickled carrots, and fresh cucumbers, jicama, cilantro and basil. They also have a slick of either house-made Thai chile or ginger aoli.

It took Bright a year to perfect the marinade and spice combinations.

"We tested it for a year. We had all kinds of groups of friends over - blue collar, artists, musicians, high school students. Everybody gave it a thumbs up. So we decided to go for it."

The sandwiches are $7.50 with a side dish of either chips or house-made Asian slaw.

47 Scott sibling eatery set to open Aug. 15

47 Scott's sister restaurant, Saint House Rum Bar, is expected to open Aug. 15 in the former Sharks nightclub downtown.

Saint House, 256 E. Congress St., will serve a Caribbean menu inspired by and infused with rum. It's the brainchild of Travis Reese and Nicole Flowers, the creative forces behind 47 Scott and Scott & Co. downtown. They had hoped to open earlier this year.

Sharks closed last June after 12 years downtown. The couple announced their plans for Saint House in August.
