Feta Spinach Bites

I got the idea for this recipe from a cooking light recipe, but simplified it significantly. I love spanikopita, but HATE dealing with phyllo sheets. I found nifty little pre-formed phyllo cups in the freezer section of my grocery store and began making these. This is another one of my standard recipes when I want to take an appetizer to a party.

Ingredients
1 Tbsp olive oil
1/2 cup chopped onion
1 generous pinch salt
1 clove garlic, minced
1 10 oz. packaged frozen chopped spinach, thawed, drained, and squeezed dry
1 large egg, beaten
1 box (15) Athenos phyllo cups
1 container crumbled feta cheese

Directions
1. Preheat oven to 350
2. Heat oil over medium-high heat
3. Saute onions until translucent
4. Add garlic, cook 1 minute
5. Add thawed, dried spinach and salt, saute 3 or 4 minutes until heated through
6. Transfer spinach mixture to bowl allow to cool for 10-15 minutes
7. Add egg to spinach mixture, mix
8. Spoon spinach mixture into phyllo cups, top with crumbled feta
9. Bake until feta begins to brown (15-20 minutes I THINK, but don't really remember, so check them from time to time).
