Cut each avocado in half and remove seed. Scoop avocado in one whole piece from the skin with a large metal spoon. Thickly slice each avocado into four large slices. Melt two tablespoons butter in a non-stick pan and place two avocado slices. Crack one egg into each avocado and sprinkle with salt and pepper; fry for about 30 seconds or until whites start to set. With a spatula, carefully flip avocado. Repeat with remaining avocados and eggs. Serve warm with a side of bacon!
