super easy lentil soup

2-3 cups lentils (any kind, or mix them up)

1 onion

1-2 cups carrot and/or beet juice

several cups water

some cilantro, chopped (optional)

1-2 Tbsp flavored vinegar (optional, today I tried riesling raisin)

rinse the lentils. add everything together, cook it all up for an hour or so. at the end, turn off the heat, add the cilantro and vinegar if desired.
