This came, I think, a long time ago from my aunt who lives in Italy. It is essentially peasant food in that it's very unfussy and simple. I like it with lots of red wine, but then for me it doubles up as an excuse to have a glass of vino while cooking. Oh, and it tastes damn fine too.
1 medium red onion, finely chopped
3 cloves of garlic, minced
400g chopped tomatoes
1 tsp mixed herbs
approx. 1 glass red wine
15og tinned tuna in spring water, drained
4 tbsp grated parmesan
500g potato gnocchi
salt and pepper to taste
Fry the onions until tender and translucent in about a tablespoon of olive oil, then add the garlic and mixed herbs and fry for a further minute. Then add the chopped tomatoes, the wine, salt and pepper. Simmer for about 10 minutes and then stir in the tuna.
Put the water on to boil for the gnocchi and turn the grill on to warm. Once the water comes to the boil, add the gnocchi and simmer for 2-3 minutes, until all the dumplings swim to the surface. Drain the gnocchi and transfer to an oven-proof dish (mine's about 30cmx20cm). Pour the tomato sauce over the gnocchi and stir it in so it's evenly covered, and then sprinkle the parmesan on top.
Place under the grill until the parmesan starts to bubble and go golden and then bring to the table. Serve with a fresh green salad.
