Method
Preparation
- Make the pickled onions by placing sliced onions in a jar or bowl. Add vinegar, water, salt, and oregano. Let it sit while you do everything else.
- Toast the dried chile de arbol in a dry pan for about 10 to 20 seconds per side, being careful not to burn them.
Making the Sauce
- Simmer the tomatoes, white onion, and garlic in water for about 10 minutes until soft.
- Blend the softened tomato mixture, toasted chiles, a splash of broth, and salt until smooth. Add tomato paste if desired.
- Pour the sauce into a pot and simmer for an additional 10 minutes, adjusting salt and heat to taste.
Assembling the Sandwich
- Slice the roll and fill it with warm shredded pork and optional refried beans.
- Place the sandwich on a plate or shallow bowl and pour hot sauce over the top, then add pickled onions.
- Enjoy immediately, using hands or fork as preferred.
Notes
Do not fully drown the sandwich until you are ready to eat to prevent it from collapsing. Optional toppings like sliced jalapenos can add extra heat.
