For the shakshuka:
Heat a cast-iron skillet or frying pan over medium heat and add the olive oil. Add the rashers and fry until they begin to brown and the fat renders. Once golden, remove from the pan and set aside. Add the onion to the same pan with the pork fat and sauté for about 10 minutes, then stir in the red pepper and cook for 5 minutes until softened. Add the garlic and chilli and cook for a further 2 minutes until fragrant. Add the tomato paste and cook for about 4 minutes until slightly caramelised. Pour in the chopped tomatoes, cumin and paprika, stir well, then reduce the heat, cover and simmer for 10–15 minutes until thickened. If the sauce reduces too much, add a splash of water to loosen it. Season to taste and stir the crispy pork back into the sauce. Lightly oil 2 heart-shaped cookie cutters and place into the sauce. Make a small well inside and crack an egg into the centre of each. Cover with a lid and cook until the eggs are done to your liking.
To serve:
Garnish with coriander and feta and serve with toasted ciabatta.
