The English muffins are being tested with a slightly more premium set of ingredients than your standard eggs, bacon (or sausage), and American cheese combo. There's the Black Forest Ham & Cheddar English Muffin and the Smoked Gouda & Bacon English Muffin.
True to the name, the Black Forest & Cheddar English Muffin includes cheddar cheese, Black Forest Ham and a fried egg on a toasted English muffin.
The Smoked Gouda & Bacon English Muffin features bacon mayo, bacon, smoked Gouda cheese, and a fried egg on a toasted English muffin
It's a solid play for the burger chain. English muffins are generally regarded as healthier than biscuits or croissants and I would certainly prefer them over burger buns for breakfast.
