You've got it right there, egg salad and crisp lettuce are indeed the key to my sandwich happiness. Bonus points for a little horseradish mixed in and a slice of provolone. I've got a drool cleanup on aisle keyboard!
I like the age-old motif of hearts and keys. It never goes out of style and always seems so genuine and proper. I also like gags involving swallowing a key like in "Arrested Development" so with these cupcakes I'm all set.
