I just sliced and avocado in half, removed the pit, and then cracked an egg into each one. Next time, I think I would use the smallest egg possible since these ran over a little bit. I think I would also doctor it with some hot sauce and garlic too, but we were so overcome with our avocado egg, we didn't add much:
1 large avocado
1 small egg
Shredded cheese for the husband
Crack the egg into each avocado, salt and pepper it to taste, adding cheese if that's your thing.
Bake until the egg is cooked to your liking at 350 degrees. I think ours took about 15-20 minutes.
We loved these for breakfast, and now pretty much all I want to do is find ways to stuff avocados and places to crack eggs into.
