I encountered this easily-solved quandary today. It took just a quick request to the chef to prepare the eggs without the muffin; and, voila, I enjoyed the delight immensely, and the spicy potatoes served alongside helped make up for the lack of crunchy -- yet soft -- English muffin as a foundation.
Also, do check that the hollandaise sauce is made with the traditional ingredients: eggs, butter, lemon juice, and a little salt!
Update: Yes, gluten free English muffins do exist; they're made by Food for Life; click here!
