LAWRENCE, Kansas – Sliced avocado, mixed greens, walnuts, grapes, dried cranberries, tomatoes, cucumbers and red onions. These ingredients are gathered in a bowl, tossed in a rice wine vinaigrette and, on this cold night at 23rd Street Brewery, placed in front of Kathy Miles. “I love the dressing,” she tells restaurant owner Matt Llewellyn. This meatless salad is a new menu item at Lawrence’s trademark restaurant, and it is selling well, Llewellyn says, mainly because most patrons add protein, raising the price from $10.99 to $13.99. Weeks ago, Kathy’s husband, the new Kansas head football coach, walked into this place for the first time and, after scouring the menu, created his own dish.
