Prepare the Creamy Sauce: In a small saucepan, melt the 30g butter over medium heat.

Add the 3 tablespoons of flour to the melted butter, whisking continuously to form a roux. Cook for about 1 minute.

Gradually add the milk to the roux, continuing to whisk to prevent lumps. Cook until the mixture thickens to a creamy consistency.

Season with a pinch of salt. Remove from heat and set aside.

Assemble the Sandwiches: Preheat your oven or toaster oven to 200°C (400°F).

Lay out the 6 slices of bread on a baking sheet.

Spread a thin layer of the creamy sauce on each slice of bread.

Place thin slices of hunter’s sausages on half of the bread slices.

Add a layer of tomato slices over the sausages.

Sprinkle chopped parsley over the tomatoes.

Sprinkle the shredded mozzarella cheese evenly over the tomatoes and sausages.

Top and Bake: Place the remaining slices of bread on top to form sandwiches.

Add a slice of cheese on top of each sandwich.

Bake in the preheated oven for 5-7 minutes, or until the bread is golden brown and the cheese is melted and bubbly.

Serve: Remove the sandwiches from the oven and let them cool slightly.

Serve warm, garnished with additional fresh parsley if desired.
