To serve:

Preheat oven to 400 degrees F. To the meat, add half of the granulated sugar, half of the brown sugar, 1 1/2 teaspoons salt, 1 teaspoon pepper and 1 tablespoon of oil. Next, combine the remaining sugars, vinegar, wine, soy sauce and fish sauce in a bowl. Taste and add salt and pepper, if needed.

Divide the meat into 2 portions. Place 2 large skillets over the highest heat possible and add 1 tablespoon of oil to each skillet. When the oil begins to smoke, add 1/2 the meat in 1 layer to each pan. Let sit until a brown crust forms, and turn to brown the other side. Browning should take approximately 2 to 3 minutes total. Set aside, drain 1 skillet of excess oil and lightly wipe down with a paper towel.

In that skillet, add 2 tablespoons of oil over high heat. When the oil begins to smoke add the onion, bell pepper and jalapeno with a pinch of salt and pepper. Cook stirring often until lightly caramelized, about 4 to 5 minutes. Add the garlic and green onions and cook for an additional 1 to 2 minutes. While the onion mixture is finishing cooking, place the 4 baguettes in the oven for 1 to 2 minutes until lightly toasted and warmed through. Add the beef and vinegar mixture to the onions, and stir to combine. Taste and add additional salt and pepper, if desired. Keep warm while you assemble the sandwich.

To assemble each sandwich, spread 1 scant tablespoon of aioli on both sides of the baguette. On the bottom half, add a small handful of watercress, then 1/4 of the meat mixture, top with a small handful of cilantro, some julienne bell pepper, a few slices of cucumber, and a few slices of jalapeno. Enjoy and serve along with 2 lime wedges (which are meant to be squeezed over the meat right before eating), Crispy Fried Onion Strings, and additional aioli in a ramekin for dipping - and enjoy!

Fire-Roasted Jalapeno Aioli:

Heat a skillet over high heat. Add the jalapeno and garlic to the dry skillet. Cook until blackened and charred on all sides, about 10 minutes. Place in a plastic bag, seal and allow to rest for 5 minutes. Then remove the stems, most of the skin, and all of the seeds and ribs from the jalapeno, and the outer layer of the garlic. Add jalapenos and garlic to a food processor or blender with remaining ingredients. Blend, taste and adjust seasoning with additional salt, pepper and cayenne if desired and enjoy!;

(Makes enough for 4 sandwiches, plus extra for dipping Onion Strings) .

Crispy Fried Onion Strings:

Fill a large heavy pot 1/3 full with oil and heat to 350 degrees F. Line a plate with paper towels. Place the flour in a large paper bag or bowl. Add the onions, toss well to coat and shake off the excess. Fry the onions until golden brown (you may need to do this in 2 batches if your pot isnt big enough), about 4 minutes. Remove to the paper towel lined plate, and immediately sprinkle generously with salt and a touch of pepper. Place a large mound on each plate and top with chopped chives. Serve with a ramekin of the aioli and enjoy!
