Preparation

Step 1

, you can’t beat a soup and sandwich dinner night.  To save a step, you can cook the onions ahead time and have the ready to go in your refrigerator.

is the kickin’ sauce I created that combines worcestershire sauce, mayonnaise, garlic powder, parsley and thyme.  Combined with the creamy cheese and a few slices of sourdough bread,  this sauce adds the finishing touch to this tasty grilled cheese sandwich.

Heat olive oil in a large skillet over medium heat. Add sliced onion, season with salt and cook, stirring occasionally for about 18-20 minutes until tender and golden brown. Stir in balsamic vinegar and cook for 1-2 minutes longer.

Butter outside of bread. In a small bowl mix mayonnaise, worcestershire sauce, garlic powder, parsley and thyme. Spread on both slices of bread. Top with cheese and onions. Top with remaining slice of bread. Toast each side of bread in a large skillet until cheese is melted. I like to use the same skillet that the onions were cooked in to infuse the flavor from the pan into the bread.

In a large skillet heat olive oil over medium heat.

Add onions, season with salt and stir to coat with olive oil.

Cook onions over medium heat, stirring occasionally to avoid burning until onions are brown and caramelized, about 20 minutes.

Stir in balsamic vinegar and cook for about 2 minutes.

Remove from heat and set aside.

In a medium bowl stir mayonnaise, worcestershire sauce, garlic powder, parsley flakes and thyme until combined. Store in the refrigerator until ready to serve.

Heat a large skillet over medium heat.
