You can see for yourself in their nutrition facts. A hamburger at McDonald's has 9 grams of fat. A cheeseburger has 12 grams of fat. The Premium Caesar salad with crispy chicken has 17 grams of fat. The Premium Southwest Salad with crispy chicken and the Premium Bacon Ranch Salad with crispy chicken both have 20 grams of fat.
On top of that, SALAD DRESSING adds EVEN MORE fat. If you want to add Creamy Southwest Dressing, it's 6 more grams of fat. The Ranch Dressing has 15 grams of fat. The Creamy Caesar Dressing has 18 grams of fat. So, if you get a salad with crispy chicken and salad dressing, you could be consuming 35 grams of fat - the fat equivalent of 4 hamburgers.
