Step 1

Preheat oven to 375°F.

Step 2

Remove sausage from casing and place in a large, non-stick skillet over high heat. Sauté until cooked through, breaking up sausage with a wooden spoon as it cooks. Stir in spinach until hot. Turn off heat, stir in feta, green onion, oregano, and salt and pepper to taste.

Step 3

Set fillo cups on a sheet pan and bake them until crisp and hot, about 4 minutes. Fill each cup with sausage mixture and top with an olive half.

Step 4

Serve immediately.
