Mix eggs and milk well. Add salt, pepper, herbs as desired.
Put additional ingredients in pie shell (any veggies, meats or cheeses.) Pour egg mixture over it. It may seem ready to overflow. If you have a lot in the pie shell, tap it down to let the egg settle around your ingredients. If it still seems too full, discard the additional egg mix (or use it for an omlette)
Place the pie on a cookie sheet to catch any overflow. Bake at 350 degrees for 50 minutes, or until crust and top are golden.
