Use a 6-7 cm biscuit cutter to cut rounds from each sheet of pastry. Place pastry cases into lightly greased, shallow round-based patty pans. Spoon about 1 teaspoon filling (see below) into each pastry case, top with a teaspoon of the combined egg and cream. Bake at 350° for about 20 minutes, or until golden brown.
For the asparagus filling: fry bacon until crisp, drain on absorbent paper. Add to combined asparagus, cheese and shallots.
For the mushroom filling: fry bacon until crisp, add mushrooms, cook for a few minutes, add chives, parsley and cheese.
For the cheese and pumpkin filling: fry bacon and onion until bacon is crisp, drain. Stir bacon mixture into combined pumpkin, cheese, nutmeg.
