To make these ahead, freeze them before baking in a covered container for up to 2 months. Do not thaw before baking.
2 teaspoons olive oil
8 ounces sliced mushrooms, coarsely chopped
½ cup chopped onion
1 package (10 ounces) frozen chopped spinach, thawed and squeezed dry
2 garlic cloves, peeled, minced
1 teaspoon dried oregano
1 ½ cups crumbled feta cheese
12 sheets phyllo dough (18-by-14-inch size)
¼ cup melted and cooled unsalted butter, or more if needed
To prepare the filling: In a large nonstick skillet heat the olive oil over medium heat. Add the mushrooms and saute until they release their juices, about 5 minutes.
Add the onion, spinach, garlic and oregano. Continue cooking about 5-8 minutes more.
Combine the spinach mixture with the feta cheese and set it aside.
Preheat the oven to 375 degrees.
To assemble: Place one sheet of the phyllo dough on a work surface. Brush it lightly and in streaks with the melted butter. Place another sheet on top and brush it with butter (keep the remaining phyllo covered with a damp kitchen towel).
Cut the two layered phyllo sheets crosswise into 6 equal strips. Place a small mound of the filling (about 1 tablespoon) on the end of each strip. Bring a corner of the dough over the filling so the short edge lines up with the side edge. Continue folding the triangular shape along the strip until the end is reached.
Repeat with the remaining phyllo dough, butter and filling.
Place the triangles on a baking sheet; brush them with butter. Bake for 12-15 minutes or until the pastry is a golden brown.
Remove the triangles from the oven and serve hot or at room temperature.
Makes about 36 triangles.
