McDonald’s introduced signature crafted sandwiches a few months back and now they’ve added a pseudo trendy recipe to the lineup. Sriracha recipe sandwiches are here. Featuring a spicier themed chili pepper Sriracha Mac sauce, white cheddar cheese, crispy onions, tomato, and a baby spinach & kale leaf blend, the sandwiches are available on a quarter pounder of “seared” beef, crispy chicken, or artisan grilled chicken.
