Fish soup with zucchini zucchini

First we clean the fish, remove the gills and insides. Separate the fish fillets and put them aside for now. Put the head, bones, and spine in a saucepan, salt and cook for 20 minutes. When the broth is ready, strain it so that there are no bones left in it. 
Cut the zucchini into half rings, peel the bitter pepper and also cut it into small rings. I definitely advise you to remove the seeds from the pepper. And finely chop the onion.
In a separate saucepan, lightly fry the onion, zucchini and fillet pieces in olive oil. Then we put pepper in it and pour the wine, and then evaporate it.
Scald the tomato with boiling water and gently peel it off, and then cut it into slices and add it to the rest of the ingredients in the pan.
Then pour the broth and cook stirring for 5 minutes.
The soup is almost ready. It remains only to cut the greens and add it to each plate already.
