Chop up the bacon while it is very cold into 1" pieces. Cook the bacon on medium heat until all pieces are crisp. Once they are cooked, lay them over a paper towel to absorb the excess oil
Preheat your oven to 350F
Add the egg, half and half, salt, nutmeg, and black pepper to a small blender or nutribullet to fully mix together. Alternately you can whisk it by hand.
Add the cheese to the blender/nutribullet and mix well. Or, just whisk in the cheese.
Open up your biscuits and separate each biscuit in half by carefully separating the layers.
Lay each biscuit half in a cupcake tin and use your fingers to mold it to the cupcake tin.
Fill each biscuit 3/4 of the way up with the egg mixture. If you have extra, you can use it to make yourself a little scrambled egg snack.
Add a little bacon to each quiche. If you are using green onion, chop it up finely and add a little bit to each.
Cook for 16-18 minutes. I cooked mine for 17.5 minutes and at first I thought I burned them, but actually they were perfect when I took them out! Let them rest for a little bit before you remove them from the baking dish.
