Made these for the party also and they were good - add more cheese for a real creamy puff.
1 (10oz) pkg frozen spinach thawed
½ c crumbled feta cheese
1/4 c minced onions
1 tbsp olive oil
1 tsp ch. dill
1 tsp minced garlic
salt and pepper
2 lg eggs
1 sheet Puff Pastry
Using your hands squeeze spinach dry until all liquid is gone. Mix spinach with next five ingredients. Season to taste with salt and pepper. Fold one egg into mix. Set aside.
Take out pastry and open it on counter. Cut into 3 equal strips, cut each strip into 6 squares, repeat. Place these squares into muffin tins, pressing bottoms and sides but leave corners sticking out. Divide filling between cups. Fold corners over, touching and pinching together a little.
Beat remaining egg and brush over pastry to give it a sheen. Bake until golden and puffed - about 25 minutes. Transfer to wire racks to cool for 10 minutes. Run knife around edges to loosen. Turn out to cool slightly before serving.
Sorry about the phone pic :)
