In a large skillet heat the olive oil and, when hot, saute the onion, bell pepper and poblano until very soft, 6 to 8 minutes. Add the garlic, Southwest Essence, salt, and oregano and cook for 2 minutes. Remove from the heat and allow to cool to room temperature.
Preheat the oven to 350 degrees F.
In a large mixing bowl, combine the cooled vegetable mixture, sirloin, chorizo, tortilla chips, eggs, and heavy cream and mix gently but thoroughly until well-combined. Transfer the meat mixture to a 6 by 9-inch loaf pan and pat the top to form a smooth loaf shape.
Place the chili sauce, pepper jelly, chipotle peppers and adobo sauce in the bowl of a food processor and process until smooth. Spoon about 2/3 of the glaze evenly over the top of the meatloaf and reserve the remaining sauce on the side. Transfer the meatloaf to the oven and bake until an instant-read thermometer inserted into the center registers 150 degrees F, about 1 hour. Remove from the oven and allow to rest for about 10 minutes before serving. When ready to serve, slice into 3/4-inch thick slices and serve with the Cheddar Mashed Potatoes, passing the remaining glaze around the table for guests who might like a bit more sauce.
