Well wash carrots and grate on a coarse grater. Do the same with the beet. Cut the onions into thin half rings.
Transfer the vegetables into a saucepan, add sugar, oil and salt, bring to a boil, reduce heat and cook for 35 minutes. Then add the vinegar, mix well and continue to cook for another 5 minutes. Ready salad spread on sterilized jars and roll.
