  • 2 teaspoons unsalted butter divided

  • 1 tablespoon fresh thyme

  • 1 yellow onion sliced thinly
  • 16 oz mushrooms

 - I used cremini

  • 2 tablespoons sherry

    or white wine

  • 3 ounces Manchego cheese shaved

  • 2 cups Fresh baby spinach stems removed
  • 2 tbsp 
Fig jam or chutney
  • 8 slices Sandwich bread of your choice


  • In a heavy skillet, melt 1 tablespoon of butter. Add sliced onions and mushrooms. Season with salt and pepper. Cook on medium heat until browned and caramelized.
  • Add sherry and continue cooking until sherry has evaporated. Stir in fresh thyme.
  • Assembly
  • Butter one side of each slice of bread.  On the non-buttered side, spread a thin layer of fig jam or chutney on only one slice.  Layer 1/4 each of the mushroom-onion mix, fresh spinach, and Manchego cheese. Top with the second piece of bread, buttered side out.
  • Place the sandwich butter side down in a panini maker or *heated skillet.  Cook sandwich 7 to 10 minutes or until the bread is browned and the cheese is melted.



You can use a hot skillet if you don't have a panini maker.  After placing the sandwich in the pan, top it with another pan to lightly press the sandwich.
I used slightly thin sourdough bread.  You can use any mild tasting bread.
