Vegetable & Feta Quiche

I made a delicious, very simple quiche last week:

9 in pie crust
3 eggs
1 T. flour
2 c. vegetables (I used generous half cups each of sliced mushrooms, chopped fresh spinach, chopped      scallions and broccoli florets, plus a little red pepper -- lots of combinations would work)
1/2 c. crumbled feta cheese
1 1/2 c. milk
garlic
salt, pepper

Bake crust for a 5-7 minutes at 450 to set.  Lower oven to 350.  Mix eggs, milk and flour.  Add vegetables and garlic and then cheese.  If this combination of vegetables and cheese does not seem to you to have enough flavor, add more garlic or try a feta with garlic or herbs.  Bake at 350 for at least 50 minutes.  It is done when knife inserted in center comes out clean.

Reheats very easily. I have not made quiche in ages and this reinterested me in this old standby.
