Baltimore's Nikki Lewis will compete on Thursday night's episode of "Supermarket Superstar," the new Lifetime show in which hopeful food entrepreneurs compete to get their products on grocery store shelves. The show is hosted by Rosedale native Stacy Keibler.  

Lewis is the developer of Mallow Crunchies, a marshmallow treat she sells at area farmers markets as well as at The Mallow Bar, her own dessert cafe in Rosedale.   

Each week on "Supermarket Superstar," three contestants compete for $10,000 in cash and $100,000 in product development, with an ultimate goal of having the A&P supermarket chain put the winning contestant’s product in its stores.

The "Snacks" episode of "Supermarket Superstar" with Lewis airs Thursday night at 10:30 p.m. on Lifetime (Channel 36 on Baltimore Comcast, check listings here.)
