Triple Decker Burgers with Cheese Sauce

 This was made by Alex Guarnaschelli on the TODAY SHOW - she made homemade burgers and they were triple stacked -which is just way to much meat for us so we chose to make them single sliders. Below is only the recipe for the sauce and the pickled onion which was a really great addition. We will definitely make this again. If you want the full recipe just google it. To assemble burger sauce on bottom bun, then burger, then sauce, then onion and top roll. Don't worry about the extra sauce on the plate you will be dipping!!

FOR THE SAUCE:

• 3/4 cup heavy cream
• 1 tablespoon Dijon mustard
• 3/4 cup sharp cheddar cheese, finely grated
• 1/4 cup finely grated Parmesan cheese
• 2 tablespoons Worcestershire sauce
• 1 tablespoon low-sodium soy sauce
• 1 teaspoon hot sauce, such as Tabasco
• 1 large clove garlic, grated
• 
  

In a medium pot, bring the cream to a simmer over medium heat. Stir in the mustard, cheddar, Parmesan, Worcestershire, soy,Tabasco and the garlic.

Take care to sprinkle the cheese so it doesn't clump as it melts in the cream. Keep warm.

FOR THE PICKLED ONION:

• 1 medium red onion, peeled and cut into thin rounds
• 
  

Add the onion slices to the grill. Cook over medium-high heat, 2 to 3 minutes. Add 1 tablespoon of pickle juice. The onions should be tender.
