Preheat the oven to 375 degrees Fahrenheit.
In a medium bowl, whisk the eggs, milk, salt, pepper and nutmeg together.
In an 8-inch baking dish, add the broccoli and pour the whisked egg mixture over top.
Sprinkle the three cheeses over the baking dish. And with a fork, gently mix the ingredients together so the cheese gets dispersed throughout the quiche.
Roughly chop the cooked, crispy bacon to create crumbled pieces. Sprinkle crumbled over the top of the quiche.
Bake for 30-40 minutes, or until it's puffed in the center and a knife inserted in the center comes out clean.
Let cool slightly and enjoy!
