Cut the zucchini into slices lengthwise and the tomatoes - into wheels. Put the parsley, dill, garlic, olive oil and salt in a blender and blend it into a thick sauce.
In an oiled baking dish, arrange a layer of zucchini, layer of tomatoes, pieces of feta cheese and the mixture of spices. Continue until out of ingredients, it's preferable if you finish off with a layer of zucchini.
Bake the dish at high heat for about 40 minutes and then add a mixture of beaten eggs and yogurt. Put it back in the oven for another 20 minutes.
Serve the zucchini with tomatoes warm, although they also taste great when cooled. The products are for a medium-sized oven dish.
