This sauce starts with olive oil and finely chopped garlic, then tomatoes simmer until the oil separates from the pulp. Tuna is mixed in off heat, then the pasta is tossed with parsley and served immediately.

Method
- Put the olive oil and chopped garlic in a small pan over medium heat. Cook until the garlic turns a pale gold.
- Add the tomatoes with their juice, stir to coat, and keep at a gentle, steady simmer about 25 minutes, until the oil floats free from the tomatoes.
- Drain the tuna and crumble it with a fork. Turn off the heat and mix the tuna into the tomatoes. Taste and adjust salt if needed, add black pepper, add the butter, and mix again.
- Toss the sauce with cooked drained pasta. Add parsley, toss again, and serve at once.
