FAQ
Is the Croissan'wich healthier than a biscuit sandwich?
It can be slightly lower in calories and sodium than a comparable biscuit sandwich, but the croissant's butter content means it is still high in saturated fat.
Can I customize my Croissan'wich order?
Yes, you can typically request no cheese or no sausage to reduce fat and sodium, and some locations may offer egg whites as a substitute.
What is the main source of protein in this sandwich?
The primary protein sources are the sausage patty and the folded egg, with a smaller contribution from the cheese.
