Quick and Pretty Spanakopita

Preheat oven to 350.  Heat oil in the largest skillet you have.  Add onion and cook until softened.  Add garlic and cook 1 more minute.  Gradually add spinach and cook until wilted.  Transfer to a bowl.  Stir in egg, herbs, feta, salt and pepper.
Lay 1 sheet phyllo on a parchment-lined baking sheet (to keep the remaining sheets moist, cover with a damp dish towel).  Brush sheet with butter.  Repeat 2 more times for a total of 6 layers.  Spread spinach mixture on center, including liquid in bottom of bowl.  Top with 3 more buttered sheets.  Roll sides in toward the center, forming a pretty crust that curves around the spinach (dab with more melted butter if necessary to keep the edges tightly rolled).  Butter 4 more sheets and crumble over top.  Bake until dark golden, about 40 minutes.
