Tuna and Tomato Sauce with Pasta

Ingredients:

Olive oil
1/2 red onion, quartered and thinly sliced
1 - 2 cloves of garlic, thinly sliced
1 red chili, thinly sliced - de-seeded 

1 can of chopped tomatoes
Black sliced olives
Sugar
Salt
Pepper
Worcestershire sauce
Fresh basil leaves, torn (optional)
1 can of tuna chunks oil, drained and flaked
Fresh parmesan, grated
Pasta cooked as per the directions


Directions:

Heat some olive oil in a pan on a medium heat. Chuck in the onion, garlic and chili and let that sizzle for a couple of minutes until the onion starts to soften up. Pour in the tomatoes and stir in some olives. Add a splash or two of Worcestershire sauce, some sugar and season to taste. Let this simmer for a couple of minutes. If using, stir in the tuna and the basil leaves and let them heat through.

Serve on pasta and if you're using it, grate some parmesan on top.
