Cut the potatoes into small chunks. Toss in salt, pepper and oil. Add the sausages to the pan and place in a high oven for 20 minutes.
After 20 mins add the shallots, tomatoes and mushrooms and cook for a further 10 minutes.
Make gaps in the potatoes and crack the eggs into the gaps. Bake for a further 5 minutes or until the eggs are soft.
Lay a bunch of spinach down on your plate, ready to serve.
Serve onto the bed of spinach and enjoy!
