Roast chicken with potatoes and mushrooms

My neighbours had a busy weekend moving stuff etc so I cooked them a simple Sunday dinner.
The recipe is from R. C. Sidoli's "The cooking of Parma".
Forgot to take a pic though :-(

Serves 4

16 potatoes (small - medium size)
1 chicken, cut in 8 pieces
500 g mushrooms, whole

Put all ingredients in an oven dish, season with a lot of pepper and salt. No oil is required.
Bake in oven at 200°C for 1h30 - 2h, until everything is cooked.
Mix the ingredients regularly while baking.

I served this with a turnip soup and pears with star anise.

Note: the chicken legs took a bit longer than the wings.
The vegetables tasted so delicious that everybody ate loads of them.
