Preheat oven to 180°C. Line an 8-hole, 1/3-cup muffin tin with prosciutto; use 2 slices for each hole. Spray 1 side of each bread slice with olive oil and rub with garlic. Cut bread slices into 16 pieces.
Put 2 pieces of bread in the bottom of each prosciutto case. Carefully break an egg into each. Season with pepper and sprinkle each with a little thyme or chives. Gather the excess prosciutto over the top of the egg. Bake for 5-6 minutes or until eggs are cooked to your desired consistency. Stand for 2 minutes before removing from the tin.
