Heat the olive oil in a large skillet or saucepan over medium heat.
Add the minced garlic and sliced chili peppers. Sauté for 1-2 minutes until fragrant.
Add the chopped tomatoes (or canned crushed tomatoes) to the pan. Season with salt to taste.
Reduce the heat to medium-low and simmer the sauce for about 20-25 minutes, stirring occasionally, until it thickens slightly.
Meanwhile, bring a large pot of salted water to a boil.
Add the pasta and cook according to package instructions until al dente.
Reserve about 1 cup (250ml) of pasta cooking water, then drain the pasta.
Add the drained pasta to the pan with the Arrabbiata sauce.
Toss gently to coat the pasta evenly with the sauce. If the sauce is too thick, add some of the reserved pasta cooking water to loosen it.
Divide the pasta with Arrabbiata sauce among serving plates or bowls.
Garnish with chopped fresh parsley.
Optionally, serve with grated Parmesan cheese on top.
