This soup layers tender lentils with aromatic vegetables, Swiss chard , and a splash of lemon juice to create a deeply satisfying and refreshing bowl. It’s comforting yet light, and thanks to the lemon and olive oil, it tastes vibrant rather than heavy.

1 carrot, diced
1 celery stalk, diced

For heartier meals, serve over cooked grains like farro, rice, or quinoa.
