Step 1: Prepare the Crust
Preheat oven to 375°F (190°C) and grease a mini muffin tin.
Roll out the pie crust and cut into 2-inch circles using a cookie cutter or glass.
Press each dough circle into the muffin tin cups.
Step 2: Make the Egg Mixture
In a bowl, whisk together eggs, milk, salt, and black pepper.
Step 3: Assemble the Quiches
Add a pinch of cheese and desired fillings into each crust-lined cup.
Pour the egg mixture over the fillings, filling each cup about 3/4 full.
Step 4: Bake the Mini Quiches
Bake for 18-22 minutes, or until the eggs are set and the tops are golden.
Let cool for 5 minutes, then gently remove from the tin.
Step 5: Serve & Enjoy
Serve warm or at room temperature.
Store leftovers in the fridge or freeze for later.
