Make the red chili sauce. Roast the chili pods on a baking sheet at 250°F for 15 minutes, without letting them char.
Put in a bowl and cover with boiling water, and then let them sit for an hour.
Put the mixture in a blender and puree. Add the garlic, onion, cumin, oregano, salt and pepper, and blend again.
Heat 2 tablespoons of lard or oil in a pot and whisk in the flour until golden.
Strain the blended chili mixture into the pot and simmer for an hour while you prepare the green chili sauce.
For the green chili sauce, heat the oil in a pan and saute the onions and garlic until tender.
Add the chilies and saute for a couple of minutes, then add the drained beans and broth.
Turn the heat down and simmer for 45 minutes.
For a thicker sauce, dissolve a tablespoon of cornstarch in hot water and add that, then cook for a further 5 to 10 minutes.
Now it’s time to assemble the Christmas huevos rancheros!
Put the tortillas on a plate and add the fried eggs on top along with a ladle each of red and green chili sauce.
Sprinkle plenty of cheese on top and put it in a warm oven to melt the cheese.
Add the tomatoes and lettuce on top and serve immediately.
