Preheat an oven to 200°C/gas mark 6. Place the tomatoes and garlic cloves (still in their skins) on a tray and bake for 30 minutes until blackened and blistered
Meanwhile, place the chillies in a bowl and pour hot water over them. Leave for 20 minutes until pliable, then drain (reserving the liquid) and transfer to a blender
Peel the blackened garlic cloves and place in the blender along with the tomatoes. Add the salt, epazote (if using) and cider vinegar and blitz until a smooth sauce. Add the reserved chilli water until you’re happy with the consistency
Pour the rapeseed oil into a deep pan and heat to 180°C. Slice the tortillas into triangles, then fry for 3–5 minutes or until crispy. Drain on kitchen paper and season with salt
Drain any excess oil in the pan (leaving a few tablespoons) and fry the eggs sunny-side up for a few minutes until cooked to your liking
To serve, gently reheat the sauce in a large pan and, once hot, add the tortilla chips, ensuring they are fully coated in the sauce. Pour the sauce-covered chips onto a large plate or bowl and top with the 2 eggs. Finish with the feta, onion, radish and coriander, then serve with lime wedges
