Leftover Salmon Melt - cooking recipe

Ingredients

1 tablespoon butter
1 onion, chopped
salt and ground black pepper to taste
1 clove garlic, minced, or more to taste
2 cups mashed cooked salmon
1/4 cup mayonnaise, or to taste
2 tablespoons capers
1 1/2 tablespoons lemon juice, or more to taste
1 tablespoon mustard
1 tablespoon minced fresh parsley
1 baguette
1 tomato, sliced, or more to taste
1/3 cup finely shredded mozzarella cheese
1/3 cup finely shredded Swiss cheese
1/3 cup grated Parmesan cheese

Preparation

Set an oven rack about 6 inches from the heat source and preheat the oven's broiler.
Melt butter in a skillet on medium-high heat. Add onion; season with salt and pepper. Cook until softened, 5 to 7 minutes. Add garlic and cook until fragrant, about 30 seconds. Let cool slightly.
Mix onion and garlic with salmon, mayonnaise, capers, lemon juice, mustard, and parsley until combined. Season with more salt and pepper as desired.
Slice baguette on a bias into 10 or 12 pieces. Place slices on a baking sheet.
Broil for 1 to 2 minutes, watching closely that they don't burn. Top bread with the salmon mixture. Add a slice or two of tomatoes to each. Sprinkle mozzarella, Swiss, and Parmesan cheese on top.
Broil until cheese is melted and golden, 3 to 5 minutes.
