Tomato herring with cherry tomatoes

Method

• Cut the herring fillets into pieces.
• Bring tomato purée, white wine vinegar, sugar, and oil to a boil.
• Add red onion in thin rings, chopped cherry tomatoes, and bay leaves, and let this simmer together for 3 minutes.
• Allow everything to cool completely, and season with salt and pepper.
• Mix the tomato sauce with the herring pieces and finely chopped dill.
• Transfer the mixture to a jar or container, and add a lid.

The herring should marinate for two days in the refrigerator before serving, and is good for about 2 weeks in the fridge.
