1Heat a large pot over medium heat.
Add the diced onions and cook until they are translucent, about 5 minutes.

Pour in the low-sodium vegetable broth and bring the mixture to a boil.
Reduce the heat to a simmer and add the salt, black pepper, and dried dill.
Cut the white fish fillets into bite-sized pieces and add them to the pot.
Simmer the stew for 10-15 minutes, or until the fish is cooked through and flakes easily with a fork.
Taste and adjust seasoning if necessary.
Serve hot and enjoy your Fish and Tomato Stew.
