Finnish Fish Soup (Kalakeitto / Lohikeitto)

Finely dice both types of onion and sauté in olive oil over medium heat until translucent

Meanwhile, quarter the carrots lengthwise and slice them, then add them to the pot

After a couple of minutes, add the potatoes, cut into fairly large chunks

Pour in the vegetable broth and simmer covered until the potatoes are tender

Cut both types of fish into pieces the same size as the potatoes, add to the broth, and simmer for five minutes
