Preheat the oven to 375 degrees. Heat the olive oil in a large skillet over medium heat. Add the broccoli and cook for 5 minutes or until tender. Remove from heat.

Place the eggs in a large measuring cup and whisk well to combine. Add the milk, grated cheese, salt and pepper and whisk until incorporated.

Generously spray (12) silicone muffin cups or muffin pan with cooking spray and divide the cooked broccoli evenly between each.

Pour the egg mixture into each muffin cup as evenly as possible.

Bake the crustless mini quiche for 13-15 minutes, or until set (it's ok if they have a slight wobble). Cool for 10 minutes on a wire rack, then remove from the molds and enjoy!
