A classic Mexican torta is served on an oblong roll and can be eaten hot or cold. And though filled with many flavors, its main element is meat — sometimes stewed or grilled, sometimes crafted from cured meats like ham. Its accompaniments are usually avocado, chiles, onions, and cheese. They’re portable, spicy satisfying and worthy of the spotlight. The Volpi torta, though not traditional, celebrates Chorizo because even a classic needs spicing up once in a while.
Sprinkle the onions with a little salt in a small bowl and let sit while you prepare the rest of the torta.
Mix the pickled jalapeños and brine with the sour cream in a small bowl. Halve, pit, peel, and slice the avocado. Thinly slice the tomato and season with salt.
Spread half the pickled jalapeño crema on the bottom of each roll. Layer half of the Chorizo, cheese, tomatoes, onions, and avocado slices. Spread the remaining crema on the top bun and serve. Repeat with the remaining roll.
