NEW YORK (TheStreet) -- Papa Murphy's(FRSH) - Get Report is looking homeward for growth before it ventures abroad, CEO Ken Calwell said, and could potentially add 4,500 stores in the U.S. alone.

The Vancouver-based "take and bake" pizza chain is planning to expand in its current markets between California and Michigan before looking at some of its other location in the U.S. and overseas, Calwell told TheStreet TV at the ICR XChange conference in Orlando.

Already popular with the Generation-X and Baby Boomer crowd, Papa Murphy's is targeting the Millennial audience with marketing plans that include mobile couponing.

"Not only are we committed to really high-quality fresh ingredients," Calwell said, "but one of our biggest priorities for 2015-2016 will be to really grow our online ordering and digital marketing presence and social media presence, which are all very very important to a Millennial audience." 

The company has also expanded its product line, adding gluten-free, pan pizza, old-fashioned spicy fennel sausage and roasted garlic pies to its lineup. But its most popular is the "Goumet Delite," which has 25% less fat, 30% fewer calories, is popular with families and, Calwell says, is its best-tasting.

Papa Murphy's is using fresh, quality ingredients, which is actually beefing up its profit margins, Calwell said. That's because its highest-volume seller "Gourmet Delite," has premium ingredients that enabled the company to raise prices. Meanhwile, it has 25% less fat, 30% fewer calories, because it uses less cheese, providing built-in cost savings and further boosting margins.
