Ingredients

  • 4 whole Medium-to-large Portobello Mushroom Caps
  • 2 teaspoons Olive Oil
  • 1- 1/2 cup Panko Bread Crumbs (or See Substitution Note At The Bottom)
  • 1/2 cups Feta Cheese, Crumbled
  • 2 Tablespoons Parmesan Cheese, Grated
  • 1/4 cups Fresh Parsley Leaves, Finely Chopped
  • 1 teaspoon Dried Thyme Leaves
  • 1/2 cups Kalamata (black Greek) Olives, Roughly Chopped
  • 1 whole Roma Tomato, Chopped
  • 1 stalk Scallion, Finely Chopped

Method

  • Preheat oven to 350 F.
  • Start by wiping the mushrooms clean with a damp paper towel.
  • Next, using a spoon, scrape out the gills so the caps are hollowed and cleaned.
  • Set the caps aside.
  • Heat a pan or stove-top grill over medium high heat.
  • Brush the underside (gill side) of mushroom caps with some olive oil and place on grill or pan.
  • Cook for 3-4 minutes or until browned.
  • Brush the tops of the caps with oil while the underside is grilling, then flip and grill the tops for 3-5 minutes.
  • Place cooked mushroom caps gill side up, on a rimmed baking sheet and set aside.
  • In a small bowl, combine panko, feta, Parmesan, parsley and dried thyme.
  • In a small skillet over medium heat, cook the olives, tomatoes and scallion.
  • You should not need any oil since the olives are likely to be oiled or seasoned already.
  • Cook until the tomatoes just start to break down, about 3-4 minutes.
  • Once cooked, pour this into the panko mixture and mix well to combine.
  • Spoon heaping tablespoons (1 1/2 tablespoons or so) into each mushroom cap.
  • You may have mixture leftover, but thats OK!
  • Bake for 20 minutes, then turn the broiler on high and broil for 3-5 minutes.
  • Keep an eye on them so they do not burn.
  • The caps are done when the panko is browned and the cheese is melted.
  • Serve immediately.
  • Reheating instruction: Bake in the oven at 350 F for 10-15 minutes, or put in toaster oven for 5-10 minutes at 350 F. Microwaving will make them soggy.
  • Serving options: This can be served for two (2 caps/person) or it can be enough for 4 if used as a side dish or appetizer.
  • You can also substitute the panko for the grain of your choice: cooked quinoa, rice, barley or couscous.
