KANSAS CITY — Restaurants are putting new twists on their popular menu items.

McDonald’s Corp. is celebrating the 50th anniversary of its iconic Shamrock Shake by launching the new Oreo Shamrock McFlurry. Available beginning Feb. 19, the treat features vanilla soft-serve ice cream blended with mint “Shamrock” flavor and Oreo cookie pieces.

“We’ve been serving the iconic, cult-favorite Shamrock Shake for 50 years, and it’s become synonymous with McDonald’s ever since,” said Linda VanGosen, vice-president of menu innovation for McDonald’s. “We’re excited to serve up a new way to experience the one-of-a-kind Shamrock flavor in our new Oreo Shamrock McFlurry. Our chefs worked to get the perfect balance of Oreo cookies and mint for this new delicious dessert.”

Papa John’s is bringing its pizza dough and toppings into a new format with the launch of Papadias Italian flatbread-style sandwiches. Made from Papa John’s pizza dough filled with various ingredients, the oven-baked Papadias come in four varieties: Italian, Philly Cheesesteak, Grilled BBQ Chicken & Bacon, and Meatball Pepperoni

“The Papadia is inspired by the ‘piadina,’ an Italian folded flatbread sandwich from Northern Italy,” said Paul Fabre, senior vice-president of product innovation at Papa John’s. “It combines the original Papa John’s crust people crave along with fresh toppings, making it the best of both worlds — it’s both a pizza and a sandwich. The Papadia is great for people on the go who are looking to mix up their traditional lunch routine.”

Sonic Drive-In is spicing up its tater tots with new Tatchos. The snack features Sonic’s signature tater tots layered with cheese sauce, bacon, diced onions, jalapeños and zesty baja sauce.

“Sonic Tots have become a fan favorite over the years, and we are giving them an exciting upgrade with a fiesta of cheesy nacho flavors to create a shareable snack inspired by similar delights found in gastropubs,” said Scott Uehlein, vice-president of product innovation and development for Sonic. “What better way to warm up on a cold winter day than with a mashup of flavors from Totchos?”
