Prep Time10 minutes
Cook Time40 minutes
Servings - 4 servings

Ingredients 

  • 1 Tbsp extra virgin olive oil
  • 1 tsp balsamic vinegar
  • 1 Tbsp white sugar
  • 1 large white onion, sliced
  • 4 slices bacon, cooked until crispy
  • 2 Tbsp butter, softened
  • 1/4 cup Parmesan cheese
  • 4 slices Swiss cheese
  • 8 slices whole wheat bread

Instructions

  • In a skillet, add the olive oil, balsamic vinegar and sugar. Add the sliced onions and heat them on low, stirring often, for 30 minutes to caramelize them.
  • Bake the bacon until crispy, about 25 minutes.
  • While the onions are caramelizing and the bacon is cooking, stir together the softened butter and Parmesan cheese. Spread the Parmesan butter on the insides of the bread. Butter the outsides of the bread for grilling.
  • Once the onions have caramelized, place them onto a plate and gently pat them dry. (You don't want them to be too runny and make the bread soggy before grilling.)
  • Add a slice of Swiss cheese, some of the caramelized onions and a slice of bacon (broken in half) onto the buttered breads. Grill on a skillet or electric griddle. Flip carefully to prevent onions from sliding out!
  • Enjoy!
