Preheat the oven to 225°C (437°F) on gas setting 4.
Brush one side of the bread with some of the butter or margarine, sprinkle with grated Gouda cheese, place on a baking sheet, and bake in the top rack of the oven for 10 minutes or until the cheese has melted.
While the bread bakes, heat the remaining butter or margarine in a frying pan over medium heat and fry the eggs until the whites are set.
In a separate dry pan over medium-high heat, fry the bacon slices until crispy.
Remove the bread from the oven and arrange on preheated plates.
Top each piece of bread with one fried egg and 2 bacon slices, then season with salt and garnish with parsley.
