Cut avocado in half and scoop out flesh as one big piece. Lay the avocado half on its side (the hole should be on its side) and cut in 3-4 large pieces, keeping the shape of the hole in each slice.
Cut a hole in the center of each slice of bread big enough to fit an avocado slice. Melt 2 tablespoons of butter in a large nonstick skillet over medium heat. Add 2 slices of bread to the skillet and toast on each side, about 2 minutes per side. Place avocado slices inside each slice of bread in skillet. Crack an egg into the center of each circle. Season with salt and pepper. Cover skillet and cook until the egg is cooked to your desired doneness, about 3-5 minutes. Sprinkle cheese on top of each slice, cover with lid again and cook until the cheese is melted. Repeat with remaining ingredients. Garnish with chives.
