Self-Crusting Quiche

I don't remember what I was searching for when I found this recipe idea, but I'm sure glad I found it!  I guess self-crusting quiche is a New Zealand thing (or so the recipes I found seemed to indicate.  It's basically an egg-bake-type-thing with lots of good stuff in it and no time-consuming crust. ;)  Amos and I make this about once a week.  We cook it in a glass pie dish, cut it into sixths, and wahh-laaah! we have breakfast for three days. :)  It stores well in the fridge and heats up nicely in the microwave.

Self-Crusting Quiche 

3 eggs
3/4 cup milk
1 cup grated cheese
Various spices, salt, and pepper
1/2 cup Bisquik or other generic baking mix
1/2-1 1/2 cups vegetables and other add-ins
Additional cheese for the top, if you like a lot of cheese 

Mix everything together well in any order in a medium-large mixing bowl.
Pour into greased pie pan or 8x8 baking dish.
Cook 30-35 minutes at 385 degrees or until set.
