Meanwhile, heat a large cast iron skillet over high heat for 5 minutes. Add asparagus and serrano to the pan and arrange in a single layer. Cook, turning occasionally until asparagus and serrano are charred all over and asparagus is just cooked through, 4 to 6 minutes for thin spears, 5 to 8 minutes for thick spears. Carefully add 1 teaspoon (5ml) pork fat (or vegetable oil) to the skillet, toss to coat vegetables, and season lightly with salt and pepper. Transfer vegetables to cutting board. Once vegetables are cool enough to handle, cut asparagus into 2-inch pieces and de-seed and finely mince the serrano. Set aside.
For Serving: Sprinkle scallions and/or cilantro over the hash, and top with fried eggs (if using). Serve right away, passing warmed tortillas (if using), lime, and salsa verde at the table.
