Tuna Pasta - cooking recipe

Ingredients

1 (9 1/4 ounce) can tuna, drained
1 (1 lb) can chopped tomato with juice
2 tablespoons olive oil
1 small onion, chopped
2 garlic cloves, minced
2 tablespoons fresh basil, minced (1 1/2 tsps) or 2 tablespoons dried basil (1 1/2 tsps)
red pepper flakes
3/4 lb of your favourite pasta, cooked al dente and tossed with 1 tblsp butter (we like to eat this sauce with pasta 'curls' so the little bits of tuna can get caught in the curls)
grated parmesan cheese, for the table

Preparation

Heat the olive oil in a small saucepan and add the onion; saute onion until it is translucent, 2-3 minutes, then add tomatoes and garlic; season to taste with salt, pepper and red-pepper flakes and boil over medium heat for 10-12 minutes until thickened somewhat; add basil and simmer 2 more minutes; add tuna, turn off heat and allow to 'sit' (flavours will blend) for 5 minutes.
This makes a very thick, flavourful sauce (you can thin with a little boiling water or some of the pasta cooking water if it's too thick for your liking).
Distribute pasta amongst 4 plates and top with sauce; pass grated parmesan cheese at the table or, alternatively, toss pasta and sauce together, then serve, passing grated cheese.
Note: If you don't want your sauce to be as 'chunky', you can puree the tomatoes before using.
