1 medium courgette
4 Spanish onions
olive oil
1/4 teaspoon salt
1/4 teaspoon pepper
125 g grated cheese

Wash the courgette, cut in half lengthwise and remove the seeds. Boil the courgette in salted water for about 15 minutes, or until tender. Chop the onion and gently fry in olive oil. Hollow out the courgettes and mix the scooped flesh with the onion and the grated cheese. Season to taste and put the mixture back into the hollowed-out courgette. Bake it until light brown for about 5-10 minutes in the oven.
