½cupminced fresh cilantro
Instructions
For the cucumber sambal, toss all the ingredients together and chill until ready to serve (this can be made a couple hours or even 1-2 days ahead of time).
Preheat a grill to medium or medium-high heat. In a medium bowl, combine 1 tablespoon brown sugar, 1 tablespoon soy sauce, oil and salt. Add the chicken breasts and toss to coat the chicken with the sauce. Let it sit for 5-10 minutes.
While the chicken rests in the marinade, start a large pot of salted water to boil.
In a microwave-safe bowl or in a small saucepan, combine the broth, peanut butter, remaining 2 tablespoons brown sugar, vinegar, lime juice, remaining 1 tablespoon soy sauce, ginger, chili garlic sauce and sesame oil. Heat, stirring often, until simmering and smooth. Off the heat (or after it is done microwaving), stir in the cilantro. Season with a dash of salt, more or less to taste.
Add the noodles to the boiling water and cook until al dente.
While the noodles cook, grill the chicken 4-5 minutes per side until cooked through (about 165 degrees on an instant-read thermometer). Remove to a plate and tent with foil.
When the noodles are finished cooking, reserve about 1/2 cup of the cooking water in a bowl and then drain the noodles. Dump the noodles into a bowl or on a serving platter and toss with the warm peanut sauce. Add a tablespoon or two of the hot pasta water if needed to loosen up the noodles and sauce a bit (especially helpful if the noodles have sat for 5-10 minutes before serving).
Serve the grilled chicken with the peanut noodles (you can even top the grilled chicken with the noodles) and a heaping scoop of the cucumber sambal.
Notes
Make Ahead: the cucumber sambal can be made a couple hours (if not a day or so) in advance and kept covered in the refrigerator which can save time during dinner prep. Chili Garlic Sauce: also, if you are confused about what exactly chili garlic sauce is, it is widely available near the other Asian ingredients - similar to sriracha sauce but a bit different in flavor and texture. I use the Huy Fong brand (MSG-free) and usually buy it on Amazon since my itty bitty grocery store in town is one of the few that don't carry it. It does pack a bit of heat so go easy on it if you are lowering the spiciness of the dish (you can always add more later if you need an extra kick).
