Preheat your oven to 350°F (175°C) and grease a muffin tin with cooking spray
In a bowl, whisk up the eggs and milk, adding a pinch of salt and pepper for flavor
Toss the chopped spinach, crumbled bacon, and shredded cheddar cheese into the egg mix
Pour the egg mixture into each of the muffin cups, spreading it out evenly
Place them in the oven and let them bake for about 15-20 minutes until the quiches are set and just a tad golden
Once the mini quiches have cooled down to room temperature, they're ready to enjoy
