As for the other items, waffle chips used to be exclusive to the catering menu but are now available at the counter. Think of them like a gluten-free kettle-cooked alternative to waffle fries. Also, the fruit cup has been "improved" according to customer feedback "to feature fewer apples and more premium fruit options." There's something really funny about people getting up in arms over the amount of apples in their fruit cups, but good for them for giving the people what they want.
The other two items are catering and online order options. The Grilled Chicken Bundle is basically a build-your-own grilled chicken sandwich kit that feeds 10 and is meant to be a lighter option. The Spicy Chilled Grilled Chicken Sub Sandwich, on the other hand, features a boneless spicy chicken breast "marinated with a special blend of seasonings, grilled, thinly sliced and served chilled on a multigrain baguette with Pepper Jack cheese, baby greens, and sliced tomato" and is meant to be a bit more substantial.
But the real takeaway here is that if you order 30 nuggets on Saturday, you'll have enough leftover for Chick-fil-A on Sunday.
