I do a mediterrenean style dish
1 red pepper deseeded and sliced
1 medium onion, thinly sliced
3-ounces fresh baby spinach (half a 6-ounce bag)
1 pound cod fillets, cut into four portions
1 small courgette,
thinly sliced cremini mushrooms,
1 can chopped tomatoes
a handful of black olives
1 tsp dried oregano
1/3 cup dry white wine
2 tbsp fresh lemon juice
Preheat oven to 200 degrees. Place onions and spinach in the bottom of an 11-inch by 7-inch baking dish. Lay cod on top. Scatter courgette, peppers, olives and mushrooms on top of fish. Add canned tomatoes, oregano, white wine and lemon juice. Cover and place in oven for 15-20 minutes, until cod flakes easily with a fork.
