For the red chile glaze: Put the chiles in a bowl, cover with 2 cups boiling water and let sit for 30 minutes.
Transfer the chiles to a blender, add 1/2 cup of the soaking liquid (save the rest) and blend until smooth. Add the honey, vinegar and some salt and pepper and transfer to a bowl. If the glaze is too thick to spread on the meatloaf, add a bit more of the soaking liquid.
For the meatloaf: Preheat the oven to 375 degrees F. Line a baking sheet with parchment paper and spray lightly with nonstick spray.
Heat the oil in a large saucepan over high heat. Add the poblanos and onions and cook until soft, about 4 minutes. Add the garlic and cook for 1 minute. Add the cumin and cook 1 minute longer. Remove from the heat and let cool slightly,
Whisk the eggs with a splash of water in a large bowl. Sprinkle with salt and pepper and add in the ground chuck and ground pork, the cooled onion mixture and the chips and cilantro; mix until just combined.
Transfer the meat to the prepared baking sheet and form into an oval loaf about 6 by 12 inches. Bake for 45 minutes, then begin to brush with a good amount of the red chile glaze. Bake, glazing occasionally, until the meatloaf reaches an internal temperature of 160 degrees F, about 15 minutes longer.
