Arrange the tortilla strips on baking sheets, spray with cooking spray and season with salt. Bake to deeply golden brown, 10 to 15 minutes.
Heat the oil, 2 turns of the pan, in a large, deep skillet over medium-high heat. Add the chorizo and brown, crumbling the meat. Add the beef and continue to brown and crumble the meat. Add in the beans, coriander, cumin, garlic, onions, poblanos and ancho puree and cook together a few minutes to combine the flavors.
Layer half of the tortilla strips in a casserole dish and top with the chorizo and beef mixture. Cool and store for a make-ahead meal (store the remaining tortilla strips in a foil pouch until using), or bake to serve. To bake, top the room-temperature casserole with the remaining tortilla strips and the cheese and bake at 375 degrees F until bubbly and hot through, 40 to 45 minutes.
Top the casserole with the pickled jalapenos, lettuce, tomatoes and onions and dollop the avocado cream over top (or pass at table).
