Healthy Caramelized-Onion Sandwich

I had other recipes waiting to be shared with you before this one, but I simply couldn't wait for its turn. This sandwich is one of the best breakfast meals that I have ever prepared in my life! I personally adore caramelized onion, but its combination with the other ingredients was something that I cannot put into words! I will wait for you to make it and share your heavenly experience with me :)
Servings: 2 yield(s)
Prep Time: 30 mins
Cook Time: 5 mins
Total Time: 35 mins
Ingredients
  • 2 onions
  • 2 tbsp balsamic vinegar
  • 1/2 tsp honey
  • 1/3 tsp salt
  • 1/4 tsp black pepper
  • 4 eggs
  • 4 slices of mozzarella
  • 4 handful of green salad
  • 2 tbsp mustard
  • 1 tbsp cooking cream or sour cream
  • 8 pieces of healthy bread (protein or wholemeal)
Instructions
  1. Chop the onions and fry them for 20 minutes on a low temperature, or until it gets translucent. Fry it for another 10 minutes on a medium temperature or until it gets brown. Pour the vinegar, honey, salt and black pepper and stir for another 5 minutes. Set aside the caramelized onion.
  2. Fry the eggs one by one. Prepare a spread by mixing the mustard and the sour cream.
  3. For each sandwiche: place a slice of bread, then some mustard-cream spread, then some green salad, than an egg, then a thin slice of mozzarella (I use toast mozzarella) and then add some caramelized onion and cover it all with another piece of bread.
