Preheat the oven to 400°F | 200°C. Lightly grease a large 18x13-inch sheet pan or tray with non stick cooking oil spray.
Arrange the sausages, bacon pieces and mushrooms on the tray. Drizzle each mushroom with garlic butter and bake for 10 minutes, until sausages begin to change to a golden brown colour, and the bacon begins to crisp on the edges.
Carefully remove the pan from the oven and add the tomatoes and asparagus, stirring them through the pan juices. Move the ingredients around to make 4 wells on the pan and crack an egg into each well.
Return the pan into the oven and bake for a further 10 mins, or until the eggs are done to your liking.
Season with salt, pepper and dried parsley. Serve with toast or fresh bread.
Notes
*Increase eggs to 8 if desired. Make sure your pan is large enough.
