Toasts with salmon tartare spiced with horseradish

Dice the salmon and place in a bowl. Finely chop the red onion and add to the bowl with chives. Mix in goat cheese, wasabi, lemon juice, and season with salt and pepper. Let rest. Butter bread slices on both sides and toast in a pan or oven (200°C, about 5 min) until crisp. Place on a platter, spoon tartare on top, and garnish with herbs.
