Here's how you make a cucumber sandwich. Get a French baguette, cut it in half like a hoagie, finely dice cucumber and mix it with shredded carrots and diced jalapeno before quick pickling with cilantro, salt, pepper, garlic and lime juice. Let those sit for like 10 minutes. Take some chicken and marinate it with soy sauce, garlic, ginger, etc. Broil that shit, shred it up, stuff into sandwich and top with pickled veg

Finish by cutting some mayonnaise with sriracha and a bit of lime juice until it's drizzling consistency (salt and pepper to taste), and drizzle over the top of sandwich, top with more cilantro
