- ▢ ¼ teaspoon salt
- ▢ 1 pound (450 grams) spaghetti

Instructions
1. Boil the Pasta Water
Fill a large pot with water and place it over high heat. Cover with a lid so it boils faster.
2. Cook the Anchovies and Onion
In a large skillet, add olive oil and anchovy fillets. Cook over medium-low heat, stirring until the anchovies completely dissolve into the oil.
Increase the heat to medium and add the sliced onion. Cook gently for 7–10 minutes until soft, translucent, and lightly golden. Do not let the anchovies burn.
3. Make the Tomato Sauce
Stir in:
- Tomato passata
- Black olives
- Capers
- Dried oregano
- Red pepper flakes
- Salt
- ½ cup water
Let the sauce simmer for 8–10 minutes.
4. Cook the Spaghetti
By now, the water should be boiling. Add salt and cook the spaghetti according to package instructions until al dente.
Before draining, reserve 1 cup of pasta cooking water.
5. Add the Tuna
When the sauce is ready, stir in the drained tuna, breaking it up gently.
Simmer for 1–2 minutes just until heated through.
Taste and adjust seasoning. If the sauce feels too thick, add half a ladle of pasta water.
6. Combine Pasta and Sauce
Drain the spaghetti (remember to keep some pasta water).
Add the spaghetti directly to the sauce. Toss everything together, adding extra pasta water if needed to create a silky, lightly creamy finish.
Serve immediately while hot.

Add olive oil and anchovy fillets to a skillet and cook until the anchovies dissolve. Add sliced onions and cook until soft and lightly golden
