1 1⁄3 cups crème fraîche
1⁄2 cup crumbled cotija cheese

1. Toast guajillo chiles on a baking sheet in a 350° oven for 5 minutes. Soak in warm water until soft, about 30 minutes. Drain. Purée chiles, broth, cumin, 2 cloves garlic, bay leaf, and salt. Heat olive oil in a skillet over medium-high heat. Brown steak and chorizo in 2 batches, about 5 minutes each. Drain. Return to skillet with purée; simmer on medium-low until thick, about 15 minutes. Chill.
2. Cook bacon in a skillet over medium heat until just crisp, 6–7 minutes. Transfer to a pot; reserve fat. Add remaining garlic, black beans, half the tomatoes and onions, ancho and chipotle chiles, and 5 cups water; bring to a boil. Simmer over medium-low heat, partially covered, until soft, about 2 1⁄2 hours. Let cool. Purée beans. Heat 2 tbsp. peanut oil and reserved bacon fat in a skillet over medium-high heat. Fry bean purée until thick, 8–10 minutes. Season with salt.
3. Mix remaining onions, remaining tomatoes, chopped cilantro, lime juice, walnut oil, avocados, serrano chiles, and salt to make an avocado relish. Pour peanut oil into a pot to a depth of 2"; heat to 350° on a deep-fry thermometer. Fry tortillas until crisp, about 1 minute. Drain on paper towels; sprinkle with salt.
4. Preheat broiler. Heat beef and beans. Divide chips between baking sheets; top each chip with beans, beef, and monterey jack; broil briefly to melt. Top each nacho with avocado relish, crème fraîche, cotija, jalapeño, and cilantro sprigs.
