Step 1

Put pasta water on to boil: Heat 2 quarts of salted water (1 Tbsp kosher salt), to a boil. While heating the pasta water, prep  the ingredients.

Step 2

Stir drained tuna with tomato, olives, onion, parsley, capers, lemon juice, olive oil, salt, pepper: Place drained tuna in a medium bowl. Stir with a fork to break up the largest chunks of tuna. Add the tomato, olives, red onion, parsley, capers, lemon juice, olive oil, salt and pepper. Stir to combine.

Step 3

Boil pasta until al dente: When the pasta water comes to a boil, add the pasta and boil, uncovered, on a rolling boil until al dente (cooked through, but still a little firm to the bite). Reserve 1/4 cup of the pasta water.

Step 4

Add pasta to tuna mixture, sprinkle with Mozz: Drain the pasta and immediately add the pasta to the tuna mixture.Sprinkle with the grated Mozzarella cheese and stir until everything is well combined. If the pasta seems a little dry, add some of the reserved pasta water and/or some more olive oil. Serve warm.
