Prepare Salsa Roja: Add the tomatoes, two of the onion halves, and the garlic to a dry pan over high heat. Toast the chillies in a separate pan for 1–2 minutes until fragrant, then soak them in boiling water. Blend the charred vegetables and soaked chillies with water to desired consistency, season with salt.
Prepare Salsa Verde: Blend drained tomatillos with jalapeño, 80% of the coriander, lime juice, and a pinch of salt to desired consistency. Refrigerate until ready to use.
Cook Beans: Cook soaked beans with the remaining onion half, bay leaf, and salt in a pressure cooker for 25 minutes or simmer in a pot for about 1.5 hours until tender. Mash and adjust seasoning.
Assemble Dish: Toast tortillas, fry eggs, and place on plates. Top each with a fried egg, surround with both salsas, and serve with mashed beans on the side. Garnish with fresh coriander.
