Prepare Water for Pasta: Fill a large pot with water and bring to a boil.
Chop Tomatoes: Chop the cherry tomatoes into 4 quarters and set aside.
Cook Pasta: Once the water comes to a boil, add 1 Tbsp sea salt, quickly stir and allow to dissolve. Add the fusilli pasta and set the timer for the time indicated on the packet.
Start the Sauce: Heat approx. 5 Tbsp of EVOO in a saucepan on medium heat and add 1-2 Tbsp of water. Add the crushed garlic and stir. Let it cook over medium heat until it becomes golden, then add cherry tomatoes and mix.
Add Tomatoes and Capers: Crush the whole peeled tomatoes then use the tomato crusher to crush the cherry tomatoes as they simmer too. Next, add the capers, crushed peeled tomatoes and stir.
Add Tuna: Add the tuna, breaking it down into small pieces and stir to allow it to meld with the flavors of the sauce.
Season the Sauce: Add a generous amount of chopped parsley, and a sprinkle of salt, and pepper. Continue to stir the sauce while breaking up the tuna chunks as much as possible.
Combine Pasta with Sauce: Once the pasta is cooked, strain the pasta and add it to the sauce. Reserve a mug of pasta water and add a portion to the sauce and pasta. Stir the mixture for a minute then turn off the heat and give the pasta a toss until all the ingredients combine well.
Serve: Scoop the desired amount of tuna pasta onto a plate, top with some fresh parsley, a sprinkle of chilli flakes (optional)…and eat up!
