Spinach & Cheese Calzones - cooking recipe

Ingredients

1 teaspoon olive oil
1 small onion, chopped
1 garlic clove, minced
3 cups fresh spinach, chopped
1 cup low-fat ricotta cheese
1/2 teaspoon nutmeg, ground
1/2 teaspoon salt
1/8 teaspoon cayenne pepper, to taste
1 egg yolk
1/2 cup feta cheese, crumbled
1 tablespoon yellow cornmeal
10 ounces pizza dough, refrigerated
1 cup marinara sauce

Preparation

Preheat oven to 375 degrees.
If making Pizza Dough start the dough first so it can rise while you make the filling.
Heat oil in a large skillet and cook onion, covered, over medium-low for about 5 minutes. Stir in the garlic and cook, uncovered, for 1 minute. Stir in the spinach and cook until wilted, about 2 minutes.
Transfer vegetables to a mixing bowl and stir in the ricotta, nutmeg, salt and cayenne. Then stir in egg yolk and feta until mixed.
Sprinkle a large baking sheet with the cornmeal (you may need 2 baking sheets for all 4 calzones). On a flat surface, roll or pat the pizza dough to a rough 12- or 14-inch square. Use a sharp knife or pizza wheel to cut the dough into 4 equal squares. Divide the filling among the dough squares, spooning it onto one diagonal half of each square and leaving about a 1/2-inch margin all around.
Fold the top over to make a triangle and seal the edges by pressing with a fork. Use a knife to make 3 slashes on the top of each calzone (Don't forget this step - unless you like the exploding kind of calzone).
Place calzones on the baking sheet and bake until golden brown, 25 to 30 minutes. Serve with heated marinara sauce for dipping.
