Pre-heat the oven at 180 C. Make the skillet available/ready.
Start by chopping the onions the mushrooms and cutting the sausages into small chunks.
Place the onions into a frying pan along with the chopped mushrooms, the lardons and the fresh sausages. Cook for 5 minutes and then add the spring onions. Cook on medium fire for further 3-4 min. Turn heat off and set aside. I did not think this dish needs any oil as the sausages and the lardons will release more than sufficient. Add the polenta cubes now if you choose to add these.
Chop the parsley and cut or grate the mozzarella cheese.
Place everything in the skillet.
Sprinkle the parsley, the cubed/grated cheese salt and pepper to taste along with a little fresh or dry thyme.
Break the quail eggs and place them one by one scattered around on top.
Place in the preheated oven and bake for 5 -7 minutes, longer if you are using regular size eggs.
Take out when ready and serve pretty much straight away. ***
