Turn your ho-hum leftover turkey sandwich into a gourmet lunch with our Executive Editor's go-to sandwich condiment. The best part? There's no shopping needed. This sauce can be made with ingredients found in your refrigerator. To build a spectacular sandwich, slather the sauce on toasted slices of your favorite bread. Then pile on the leftover turkey and top with thinly sliced red onion, crisp lettuce leaves, and a juicy slice of tomato.
Stir together mayonnaise, ketchup, minced peppers, horseradish, and chili sauce in a small bowl. Add salt to taste. Refrigerate in an airtight container up to 5 days.
*Sweet pickle relish may be substituted.
