Maybe added a touch too much mustard. Added 2 spears of dill pickles. Used 3 small green onions instead of 2 normal sized ones. Added 1/4 tsp salt (which I could have added maybe a tiny bit more) and about 1/2-3/4 tsp fresh ground black pepper. Put it on English muffins and tortillas instead of bread since that's what we had. Forgot about the lettuce which would have been a nice touch but didn't need it. Super easy to make! Turned out really good and I'll definitely make it again!
Edit: I made this again and forgot to add the green onions but I did add paprika which was delicious! Reminds me of deviled eggs quite a bit. It's so good on a piece of sourdough toast!
