Creating these filo pastry mini quiches is a rewarding experience. Follow these simple steps to get perfect results:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Muffin Tin: Grease a muffin tin with cooking spray or a little butter to prevent sticking.
3. Layer Filo Pastry: Lay one sheet of filo pastry on a clean surface. Brush lightly with melted butter. Repeat this process, layering and buttering each sheet until you have 4 layers.
4. Cut Filo Sheets: Using a sharp knife, cut the layered filo sheets into squares large enough to fit into the muffin tin cups, allowing some edges to hang over.
5. Form Cups: Gently press the filo squares into the muffin cups, creating little pastry cups.
6. Prepare Filling: In a mixing bowl, whisk together the eggs, heavy cream, salt, and pepper until fully combined. Stir in the grated cheese and cooked vegetables.
7. Fill Pastry Cups: Pour the filling mixture into each filo pastry cup, up to about ¾ full.
8. Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes or until the filling is set and the pastry is golden brown.
9. Cool and Serve: Let the mini quiches cool in the tin for a few minutes before gently removing them. Serve warm or at room temperature.

These straightforward steps will result in a delicious treat that you and your guests will adore!
