Preparation
Cut the tomatos to half and grill them for 10 minutes in 200C in a tray which keeps the tomato liquid.
While tomatos are in the oven, cut the onion to thin slices, break the Feta cheese into pieces with your fingers, rinse the olives, chop the oregano leaves to release their aroma, and cook the pasta in well-salted plenty water until al dente.
Mix all ingredients in a bowl and serve immediately.
