Turkey-Stuffed Portobello

The last time I made these delicious little beauties, I was amazed that I actually liked loved them because they contain two of my most hated ingredients - onion and mushroom. This time, however, I was surprised when K told me that this is one of his favorite meals. I mean, I knew that he liked it, but to be added to a favorites list means that it must be something special!! It's a great feeling to prepare a dish that others rave about, and this one will definitely make an appearance more frequently than once every four months in the future!!

Ingredients

• 1 tablespoon extra-virgin olive oil
• 1 sweet onion, thinly sliced lengthwise
• 2 teaspoons cider vinegar
• 3/4 teaspoon ground sage (I didn't have this, so I left it out)
• 1/2 teaspoon chopped fresh rosemary
• 1/2 teaspoon salt
• 1/2 teaspoon freshly ground pepper
• 1/8 teaspoon ground nutmeg
• 1 pound 93%-lean ground turkey
• 4 medium-large portobello mushroom caps, gills removed
• 1 tablespoon Worcestershire sauce
• 1/2 cup finely shredded fontina cheese

Preparation

1. Position rack in the lowest position; preheat oven to 400°F.
2. Cook oil and onion in a large skillet over medium heat, stirring occasionally and reducing heat as necessary to prevent scorching, until softened and starting to turn golden, about 20 minutes. Stir in vinegar.
3. Meanwhile, combine sage, rosemary, salt, pepper and nutmeg in a small dish. Place turkey in a medium bowl and sprinkle the spice mixture over it. Gently mix with hands to combine. Form into 4 equal balls. Rub mushroom caps on both sides with Worcestershire. Place one turkey ball in each mushroom cap, patting down to fill the cap. Place on a baking sheet.
4. Bake the stuffed mushrooms on the bottom rack until the mushrooms begin to soften, about 20 minutes. Remove from the oven, spread the onion mixture over the filling and top with fontina. Continue baking until the cheese is melted and golden and the turkey is cooked through, about 10 minutes more.
