Simple IngredientsSecret Smashburger Sauce Recipe

• Mayonnaise| I like to useChosen Foods Avocado Mayofor a healthier alternative and better flavor. However, you may use whatever mayo is your favorite.
• Sweet Pickle Relish| Adds a sweet taste and a subtle tanginess, or chop up bread and butter pickles or even use dill pickle relish.
• Dijon Mustard| Tangy and sharp dijon gives a kick to this sauce.
• Lemon Juice| Freshly squeezed for the freshest flavor.
• Seasoning Salt| Enhances the flavor of any dish. I like this organic one without any MSG.
