Grilled chicken sandwiches compared across 4 chains
4 of the largest US chains list 5 menu items in this group (grilled chicken sandwiches). Among single orders, the lightest is the Chick-fil-A Grilled Chicken Sandwich (206 g) at 390 calories and the heaviest is the Chick-fil-A Grilled Chicken Club Sandwich (w/ Pepper Jack, 237 g) at 520 calories.
Each chain sets its own portions, so a “medium” at one chain can be much larger than at another, and some chains give values for one piece or one slice rather than a whole order. The size column shows the serving each row’s values are for, as the chain publishes it (pieces, weight or volume); compare servings, not size names. Values are for the standard recipe.

There is one row per item. Calories show the range across every size the chain lists; the other columns are for the size and serving shown, usually the chain’s first listed size. A blank cell means the chain does not publish that value. Each item’s page has every size with full nutrition facts, and allergens where the chain publishes them.
