In a pan or skillet, heat 4 tablespoons olive oil and 1 tablespoon sesame oil.
Add the 4 eggs, peeled and hard-boiled, and brown on all sides. Use tongs to help you in this. Transfer to plate and reserve.
To the same skillet, add 2 small shallots, minced and 2 tablespoons harissa.
Season with ¾ teaspoon salt , or to taste, and cook for a minute or two, until softened.
Add 2 cups crushed tomatoes and cook for 2 minutes.
Add 1 teaspoon Worcestershire sauce, ¼ teaspoon ground cumin and ½ teaspoon coriander seeds and ⅛ teaspoon black pepper. Cook until the sauce is chunky. Taste it and adjust salt and seasonings. If needed, add a few tablespoons of water (or coconut milk) to thin the sauce.
Add the blistered eggs to the skillet. Cook for a minute or two.
Cut eggs in half and serve immediately with sauce and crusty bread or toast.
