This is one of my ‘all time favorite’ grilled sandwich with lot of possibilities for variations. You can use your choice of bread and cheese for this recipe. Also try this recipe without chicken for an amazing Veggie Cheese Melt!

  • Transfer the grilled chicken thighs to a paper towel to remove excess oil.
  • Sautéed Veggies– In the same skillet, add a tbsp. butter and sauté the onions, mushrooms and spinach with a dash of salt and pepper for about 5 minutes till the spinach leaves wilt and mushrooms are soft. You can also caramelize the onions separately if you want. Set aside the mixture once done.IMG_2012.JPG
  • Built the Sandwich- Butter one side of bread slice and on the other side place a slice of Cheddar cheese, followed by a piece of grilled chicken thigh and swiss cheese. Add 2 tbsp. of sautéed veggie mixture and another slice of Cheddar cheese and top with the 2nd slice of bread(Always butter the outer sides of bread slices for even browning).
