Preheat the oven to 200 degrees (180 degrees for a fan oven). Toast 4 slices of white bread in the toaster until golden brown. Then brush with 2 tablespoons of butter and place on a baking tray lined with baking paper. Top with 4 slices of cooked ham. Place 4 pineapple rings (can) on top.
Cut 200 g goat cheese camembert (roll) into thin slices. Arrange in a fan shape on top of the pineapple rings. Drizzle with 2 tbsp olive oil and sprinkle with 1 tsp dried oregano. Bake in the hot oven on the middle shelf for 12-15 minutes. Then serve immediately.
