Need lentil soup for one? Allow us to suggest this super fast recipe for a "can"-do dinner. It uses canned lentils and store-bought vegetable or chicken broth—that's why it's so fast. The recipe starts with gently cooking finely chopped onion, carrot, and celery; this is called a mirepoix or aromatic base. The vegetables are cooked until soft, just like they are in a big-batch lentil soup. Then, the stock is poured into the pot and simmered briefly to develop the flavor before canned lentils are added. This is when the soup is ready for its final ingredient—a little red wine vinegar brings it all together.

For a healthy, delicious, quick, and easy meal for one, you really can't beat this comforting recipe. Serve with plenty of crusty bread for dipping.

Why does my lentil soup taste bland?
