PITTSBURGH (KDKA) — Primanti Bros. is known for piling their signature fries on their sandwiches, but a new addition to the menu is swapping out fries for pierogies.

Between two thick slices of Italian bread, the sandwich will have kielbasa, provolone cheese, hot grilled slaw, beer mustard, tomato and — instead of fries — Mrs. T’s Pierogies.

Toni Haggerty, long-time manager of Primanti’s original location in the Strip District, describes the sandwich as “if polka music was a flavor,” and LeeAnn Smulligan, the director of marketing for Mrs. T’s Pierogies, says it’s “a match made in sandwich heaven.”

“I don’t let them make changes to our sandwiches like this unless they’re good,” Haggerty said.

The “Polish Hill sandwich” will be available at Primanti Bros. locations in Pennsylvania, Ohio, West Virginia, Maryland and Michigan starting on Friday, June 8.
