The sandwich is being tested at 11 locations in Central Ohio, according to Columbus Business First.
It includes a fried chicken patty wedged between two pancake-like McGriddle patties.
Franchisee Brian Mortellaro said he devised the idea and took it up the supply chain.
"Filet-o-fish, Big Mac - both of those started with owner-operators," Mortellaro told Columbus Business First. "We took this idea up the chain and they're letting us try it out."
Existing McGriddle sandwiches include a sausage and bacon varieties with cheese and egg.
This isn't some corporate-mandated rollout. Versions of the product have been tested in other markets before, but this take was devised by Brian Mortellaro, who owns eight local McDonald's, and a small group of taste-testers including other operators.
"Filet-o-fish, Big Mac - both of those started with owner-operators," Mortellaro told me. "We took this idea up the chain and they're letting us try it out."
