Grill or pan-sear your chosen protein with a bit of oil, salt, and pepper.
Let it rest for 5 minutes, then slice thinly.
Toast the Bread:
Lightly toast the baguettes in an oven or on a skillet until the outside is crispy but not hard.
Assemble the Sandwich:

Spread mayonnaise evenly on the inside. Add a drizzle of sriracha or hoisin if desired.
Layer with your chosen protein, pickled vegetables, cucumber slices, and fresh cilantro leaves.
