Cheese Filled Triangles

3 tablespoons olive oil

1 onion, finely chopped

1 (10 ounce) package frozen chopped spinach - thawed, drained and squeezed dry

1 teaspoon salt

1 (4 ounce) package feta cheese, crumbled

½ cup cottage cheese

1 egg, beaten

1 (16 ounce) package phyllo dough

1 cup unsalted butter, melted

Heat olive oil in a medium saucepan over medium heat. Slowly cook and stir onion until tender, about 5 minutes. Mix in spinach and salt. Stir in feta cheese, cottage cheese and egg. Cook and stir until thickened, 5 to 10 minutes. Reduce heat to simmer.

Preheat oven to 400 degrees F (200 degrees C).

Unroll phyllo dough sheets one at a time on a flat surface. Brush with unsalted butter. Cut into strips approximately 5 inches wide. Place 1 tablespoon of the onion, spinach and feta mixture at one end of each dough strip. Fold the end of the strip over the filling so that it forms a triangle. Continue folding the strip in triangles until a small, triangular stuffed pastry remains. Brush with unsalted butter. Repeat with remaining phyllo dough.

Arrange stuffed triangles on a large baking sheet. Bake in the preheated oven 12 to 15 minutes, until golden brown. Serve warm.
