Sounds like my mother's Ukranian family beet soup recipe. I don't say "borscht" because it isn't traditional borscht. We start by slicing beets thin, maybe 3 lg or 4-5 small beets, chopping them into bite-sized pieces, or even shredding if you have the muscle for that. Then in a cast iron pan, using a small amount of oil and high heat, cook those beets until they begin to carmelize and blacken around the edges. Then you add more oil, lower the flame, and start adding veggies that you would use in soups such as carrots, celery (not too much), lots of onion, and a few cloves of garlic. (I also love to add fresh corn kernals, but never canned or frozen because it loses all its texture in the broth and gets mushy.) When these ingredients have started to cook (about 10 minutes) you add water or stock if you prefer. I bring this base to a boil, add a small 8 oz. can of tomato sauce (chopped fresh tomato is optional), and then simmer for about 45 minutes. I don't add the chopped kale until the end. I sometimes also add potato and/ or cauliflower depending on how hearty of a soup you want, which would go in towards the end but need more time than the kale. You can season with herbs but I don't add much other than salt and pepper.
This soup has a delicious rich flavor and is very healthy and nutrient-rich. It is also beautiful and full of purples, pinks and majentas. Personally I love served with grated parmesean on top. Good luck!
