Cook and Toss Pasta
Bring a large pot of salted water to a boil. Add the capellini and cook it for about 4 to 5 minutes, until it’s tender but still has a little bite to it. While the pasta cooks, squeeze the lemon juice into a big bowl, making sure to catch any seeds. Whisk in the olive oil, then stir in the Parmesan, parsley, lemon zest, garlic, salt, and a pinch of crushed red pepper until everything is well mixed. Flake the tuna into the bowl, breaking up any big chunks, and gently fold in the cannellini beans. Once the pasta is done, drain it and add it straight into the bowl with the tuna mixture. Give everything a good toss to combine, then serve it up right away.
