SET UP: Preheat the oven to 350 degrees F.
BROWN THE CHORIZO AND ONION: Cook the chorizo until browned in a large nonstick skillet over medium-high heat, about 8 minutes. Transfer to a 3-quart baking dish, leaving the fat in the skillet. Saute the onion in the pan drippings until golden, about 6 minutes. Stir in the beans, then transfer to the baking dish.
ASSEMBLE AND BAKE: Beat the eggs, heavy cream, and sour cream with 3/4 teaspoon salt and a couple turns of pepper. Gently pour the eggs over the meat and beans. Press the chips into the mixture so they stand up. Sprinkle with the Cheddar and bake until the eggs are just set, about 45 minutes. Sprinkle with the cilantro and serve with salsa.
