Preheat your oven to 400F and blind bake the pie shell as per the instructions on the box. If there are no instructions for blind baking, see notes.
While the pie shell is blind baking, prepare the filling.
Cut off the top 2 inches from the asparagus and reserve to place them on top. Finely chop the rest of the asparagus stems.
Place a large frying pan on medium-high heat. Drizzle in the olive oil. Add the chopped asparagus stems and the chopped onion into the pan. Cook until the onions are translucent. Take the pan off the heat.
In a bowl, whisk together the eggs and the milk. Add the salt, pepper, and oregano to the bowl and whisk until well combined.
Stir the chopped ham into the cooked veggies and then pour the filling ingredients into the blind baked pie shell. Transfer the pie plate to a baking tray to prevent any messes in the oven.
Sprinkle the grated cheese on top of the ingredients. Gently pour the egg mixture over the cheese to fill the quiche. Place the asparagus tops on top of the quiche in a circular pattern.
Place the quiche into the preheat oven and turn the oven temperature to 375F. Bake for 40-45 minutes. The quiche is ready when a knife inserted in the centre of the quiche comes out clean.
