Mince the onion and garlic.
Heat olive oil in a pan and sauté the garlic and onion.
Add the sausages and green chili peppers, and stir-fry together.
Pour in the tomato sauce and season with salt and pepper.
When the sauce starts to boil, reduce to medium heat and crack an egg into the center of the pan.
Cover and cook until the egg is soft-cooked.
