Spaghetti with Feta Sauce

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

Bring salted water to a boil in a large pot and cook the whole wheat spaghetti al dente according to package instructions. Then drain.

Meanwhile, finely dice the celery stalks and onions. Halve the cherry tomatoes. Place the prepared vegetables together with the olive oil, chopped tomatoes, salt, and pepper into the baking dish and mix well. Place the whole feta block in the center on top of the vegetables.
