Heat a saucepan over medium-low heat and saute the garlic in olive oil. To prevent it from browning and cooking too quickly, add 3 tablespoons of water. When the water has evaporated, add the diced tomatoes, chilli flakes and 1/2 cup of water. Let it simmer for 10-15 minutes, then stir through the oregano and season to taste.
Using a spoon, make 6 wells in the tomato sauce and crack the eggs into each one. Cover the pan with a lid or aluminium foil and cook for 8-10 minutes on low or until eggs are cooked to your liking.
