The sandwich, which launched Dec. 31, is the restaurant chain’s latest item to be grilled using fresh onions. Another limited-time offering, the cheddar bacon onion sandwich, debuted in October. It was available with angus beef or grilled chicken and included slivered, caramelized onions.
The grilled onion cheddar burger is a beef patty served with onions and a white cheddar slice on a toasted bun. It’s on McDonald’s extra value menu, according to Tyler Litchenberger, communications manager, McDonald’s USA.
