This is definately for mustard lovers, mind you I don't actually measure mustard - I just squirt it and use what suits my family. I would up the eggs to 4 eggs for 4 sandwiches.
Are you sure about the measurements of the mustard. It was horribly mustardy.
I just made this for my lunch and I love this recipe! With the exception of the Dijon mustard and horseradish, it's the closest to what my mother always made, and I absolutely love the addition...
