1 pound penne (such as Barilla or de Cecco fine)
1/4 cup extra virgin olive oil (EVOO), plus more for tuna
5-6 anchovies, in jars with red pepper, if plain anchovies add 1 teaspoon red pepper flakes
4 large cloves garlic, grated or finely chopped
1 can tomatoes (28 ounces) (recommended: San Marzano)
1 cup chicken or seafood stock
Freshly ground black pepper
A few tablespoons capers, drained
A handful pitted black olives, oil cured or kalamata, chopped
1 pound tuna steak
1 large egg
1/2 cup bread crumbs
A handful flat leaf parsley, finely chopped
1/2 cup basil leaves, shredded
Bring a large pot of salted water to a boil over high heat. Add pasta and cook to al dente. Drain and keep warm.
Heat EVOO in a large skillet over medium heat, add anchovies and stir into oil until melted. Add the garlic, turn heat to low and saute for a couple of minutes. Stir in the tomatoes crushing them up, then stir in stock. Season with a little black pepper, add capers and olives and simmer a few minutes.
While sauce simmers, cut tuna into chunks and grind in food processor into coarse mixture. Pulse in the egg, bread crumbs and parsley and season with a little salt and black pepper. Remove tuna mixture from the processor to a bowl and add a drizzle of EVOO. Stir to combine. (Adding the oil will prevent mixture from sticking to your hands as you roll the balls.) Roll the tuna into small balls and drop into the sauce. Cover the pot and simmer the tuna balls in the sauce, about 4-5 minutes.
Place the pasta into a serving bowl. Add the tuna and sauce, toss to coat and garnish with shredded basil.
