There's no call to insult something like that. If they choose to eat at Chick-fil-a because they don't have time (or don't know how to cook) that's fine. They should be commended on their food choices there. Chick-fil-a has so many fatty, fried food options and they choose something grilled, with vegetables.
Besides, what toddler do you know of will choose to eat a kale salad?
