Here are the two posts that I saw:
Bacon, Egg, and Toast Cups
Baked Egg Cups
I didn't have any bacon in the house (I know, for shame...), but I did have some deli ham (Kroger Private Select Smokehouse ham) that I had just bought, so off I went.
First, I spray greased the muffin pan and the cups with some bread I had rolled flat.
Then I placed a slice of ham in the cup, a little bit of cheese, and then cracked an egg into it.
I topped each with a little salt & pepper and a couple of strips of prosciutto.
Then into the oven (375ยบ) for 20 minutes, and voila, breakfast!

Give it a try!
Enjoy,
Lorence
