This Nordic-inspired open-faced sandwich combines the rich flavors of herring, fresh vegetables, and herbs on a buttered slice of rye bread.
Spread the butter evenly over each slice of rye bread.
Ensure the butter is at room temperature for easier spreading.
Cut each slice of bread into halves or quarters, depending on your preferred serving size.
Use a sharp knife to achieve clean cuts.
Place a herring fillet on each piece of bread.
Pat the herring dry with a paper towel to remove excess moisture.
Top each piece with a few slices of red onion and a wedge of tomato.
Slice the onion thinly for a milder flavor.
Garnish with a sprig of fresh parsley.
You can also chop the parsley and sprinkle it over the top for a different presentation.
Serve the sandwiches immediately and enjoy.
Pair with a light salad or soup for a complete meal.
