How to Make It
Preheat the oven to 350°. Starting 1 inch from the stem ends, slit the chiles lengthwise and cut out the core, tapping out any extra seeds. Transfer the chiles to a baking dish, drizzle with the olive oil and season with salt. Cover with foil and bake for about 40 minutes, or until the chiles are tender.
Meanwhile, in a bowl, toss the avocado with the tomato, lemon juice and onion. Season with hot sauce and salt.
Increase the oven temperature to 450°. Uncover the chiles. Using a fork, carefully open one and insert a piece of Manchego. Sprinkle the chiles with pimentón and bake for about 5 minutes, or until the cheese is melted. Transfer 2 stuffed chiles to each plate. Spoon the avocado salsa over the chiles, top with the tortilla chips and serve warm.
