Vegetable pie

My mother's vegetable pie could easily be a main dish.  It uses cheese, so if you are not a vegan, it makes a great vegetarian meal.  I showed a picture of this a few weeks ago after a visit to RuthAnn's house, and not surprisingly I received requests for the recipe.  Mom uses Bisquick, but you can substitute your own Master Mix version if you'd like.  Here is Mom's version of the Bisquick classic:

Vegetable Pie

2 c chopped fresh broccoli or cauliflowerets
1/2 C chopped Onion
1/2 C chopped Green Pepper
1 C shredded Cheddar Cheese (about 4 oz)
1 1/2 C Milk
3/4 c Bisquick
3 Eggs
Salt and Pepper

Lightly grease pie plate, 10x1 1/2".  Cook broccoli slightly.  Mix broccoli, onion green pepper and cheese in pie plate.  Beat remaining ingredients until smooth.  Pour into pie plate.  Bake at 400 until golden brown, 35 to 40 minutes (I cook longer, more like 50 minutes).  Let stand to cool for 5 minutes.   One package (10oz) frozen broccoli; thawed and drained can be substituted for fresh vegetable.  Do not cook the frozen broccoli if used.
