1.
Preheat oven to 190°C/170°C fan-forced and brush a 6-hole large muffin tin with a little of the melted butter.
2.
Flatten each bread slice with a rolling pin until very thin. Brush both sides of the bread with melted butter. Spread one side only with VEGEMITE. Press 1 slice of bread, with the VEGEMITE facing up, into each hole in the muffin tin.
3.
Bake for 5 minutes or until the bread is slightly firm. Remove the tin from the oven and sprinkle spinach and cheese into each bread cup. Crack 1 egg into each cup. Season with freshly ground black pepper and top with the bacon.
4.
Bake for a further 15 minutes or until the whites are set. Remove from the tin and sprinkle with the chives before serving.
