I have a scrumptious old family cabbage borscht that you could leave the sugar and cooking wine out of, and adjust onions, carrots, and “whatever else” to lc veg. Other ingredients include cider vinegar, garlic++++, herbs spices flavorful bottled stuff, and whatever appeals. When this simmers all day, I drool. Have not made it this winter bc I’d eat too much. Probably can use less liquid, and bake rather than make soup, for a side dish. Interested?
Edit: this would be pretty much what Chook suggested, if baked.
