To make Italian tuna pasta start by cooking the spaghetti until it's al dente.
Then as the pasta is cooking, prepare the sauce by heating some olive oil in a skillet and sauteing of some chopped onions and anchovy fillet if using anchovy fillet.
Then add in some crushed red pepper and garlic, and stir in crushed tomatoes.
Next reduce the heat and add the capers and canned tuna, breaking up any large pieces.
After the pasta is cooked then you can drain the spaghetti and toss the spaghetti with some tuna sauce.
Then garnish it with some fresh herbs before serving or eating.
You can also add a small amount of starchy pasta water to the sauce which can help it coat the pasta better.
You can also enhance the flavor with some ingredients like chopped olives, fresh herbs, a squeeze of lemon juice or lemon zest.
If you want added texture you can top the dish with some garlic and fried breadcrumbs.
