Preheat your oven to 375°F (190°C).

In a large pot, bring salted water to a boil. Cook the pasta according to package instructions until al dente (8-10 minutes). Drain and set aside.

Heat olive oil in a skillet over medium heat. Sauté finely chopped onions and minced garlic for about 3-4 minutes until translucent.

Pour in canned tomatoes, season with salt, pepper, and Italian herbs, then stir in the drained tuna. Let the sauce simmer for about 5 minutes.

Fold the cooked pasta into the sauce until well coated.

Grease a baking dish and transfer the pasta and sauce mixture, spreading it evenly.

Sprinkle cheese generously over the top, then bake for 25-30 minutes until cheese is bubbly and lightly browned.

Let the dish cool for a few minutes before serving.
