Spaghetti with Feta Cheese Sauce

First, preheat the oven to 190–195 °C and prepare a baking dish (25 cm × 30 cm).

Bring salted water to a boil over medium heat, then cook the spaghetti according to package instructions. (In our case, the spaghetti cooked for 17 minutes.) After cooking, drain the spaghetti.

Now, dice the celery stalks and onion. Halve the cherry tomatoes. Place all the prepared vegetables into the baking dish, add olive oil, salt, pepper, and chopped tomatoes, and mix. Place the feta cheese, in one piece, on top of the vegetable mixture. Then, place everything into the preheated oven and bake for 30–35 minutes at 190–195 °C.
