All-in-one-baked mushrooms

Ingredients
2 tbsp olive oil
4 very large field mushrooms
4 slices good-quality cooked ham
4 eggs

Method
Heat oven to 220C/fan 200C/gas 7. Drizzle a little olive oil over the base of a ceramic baking dish, then pop in the mushrooms.
Drizzle with the remaining oil and seasoning. Bake for 15 mins until soft, then remove from the oven.
Tuck the ham slices around the mushrooms to create little pockets. Crack the eggs into the pockets, then return to the oven for 10 mins until the egg white is set and the yolk is still a little runny. Serve scooped straight from the dish. Great with baked beans and chips
