Vegetable stew with zucchini for winter

Preparing vegetables according to the list:
1. My zucchini, cut into small cubes with a side of about 2 cm. If the zucchini is no longer young, peel the skin and completely remove the seeds.
2. Tomatoes are also washed, cut into slices.
3. Remove the seeds in the bell peppers, rinse under running water and cut the peppers into strips.
4. Peel the onion, wash and cut into small cubes.
5. We put the vegetables in a cauldron (or other thick-walled dishes), add sugar and salt, pour in vegetable oil.
6. We send the stew to a low heat, simmer for 40 minutes, do not forget to stir occasionally.
7. When the dish is almost ready, pour in the vinegar, keep it on fire for a couple of minutes and turn it off.
8. In clean, pre-sterilized jars, we put a leaf of lavrushka, as well as black pepper with peas, and fill the containers with hot stew.
9. Roll up the jars with lids, after holding them in boiling water for a couple of minutes.
10. Turn the blanks upside down, insulate with a blanket or blanket, leave until completely cooled. Then you can put the jars in a dark, cool place for storage.

Take out the blanks if necessary and eat with an appetite!
