Simply Elegant Cheesy Broccoli Quiche

1 unbaked pie crust, 9 inch
2 Tbsp butter
2 cups chopped fresh broccoli
1 small sweet onion, diced small
1 garlic clove, grated
1 cup shredded Mozzarella cheese
1/2 cup shredded Cheddar or Guyere cheese
4 eggs, well beaten
1 1/2 cups milk
1 tsp salt
1/2 tsp black pepper
1 Tbsp butter, melted

Preheat oven to 350 degrees; put unbaked pie crust into 9 inch pie pan and set aside.
In large saucepan over medium low heat, melt butter, add broccoli and onion, stirring occasionally and cooking until just starting to get tender.
Add garlic and, stirring, cook 1 minute longer.
Turn the broccoli mixture into crust, then top with both cheeses.
In separate bowl, combine eggs, milk, salt, pepper, and melted butter; pour evenly into pie pan.
Bake in preheated oven at 350 degrees for 30 to 35 minutes, until lightly browned around the edges and center of pie feels firm.
Remove and cool for 5 minutes, then serve warm.
