Put the bulgur in a medium bowl and add the boiling water. Cover with plastic wrap and let stand until the bulgur is tender, 45 minutes to 1 hour.
Meanwhile, in a medium bowl whisk the vinegar and sugar with a generous seasoning of salt and pepper until dissolved. Add the cucumber and onion, toss well and set aside to marinate for about 30 minutes.
In a separate small bowl combine the yogurt and chili garlic sauce. Season with salt and pepper and set aside.
Drain the bulgur and put into a large bowl. Add the turkey, hoisin, scallions, ginger, garlic and chopped cilantro and mix until just combined. Form into 4 equal sized patties.
Heat a large nonstick skillet over medium heat until very hot. Lightly brush both sides of each patty with oil and place in the skillet. Cook, turning once, until just cooked through, 3 to 4 minutes per side.
Drain the pickled vegetables and toss with the whole cilantro. Spread some spicy yogurt sauce on the top and bottom of each bun and top with a burger patty and some pickles.
We lightened these burgers by cutting back on the meat and adding some texture with bulgur. Great Asian flavors in the burger, a quick picking of cucumbers and onions and a spicy yogurt sauce tie everything together.
