There is a reason the Big Mac was so popular... the special sauce! I don't know if I've ever actually had a Big Mac (I'm more of a Happy Meal girl - I'm being serious), but I was curious... what is so special about the sauce? Turns out, it is just a simple Thousand Island dressing. Wait...What's in Thousand Island dressing, you ask?
Special Sauce (Thousand Island)
1/4 cup of mayonnaise
1/4 cup of ketchup
