Baked Pineapple and Gouda Cheese Toast

Cut the toast slices into circles about the same size as the pineapple slices. Spread the butter onto the toast circles and top each with a slice of pineapple and Gouda cheese. Place the pineapple toasts on a baking sheet lined with parchment paper and bake in an oven preheated to 175°C (approximately 350°F) for about 8 minutes, until the cheese has melted.
