For marinade & dressing: Whisk all ingredients together. Pour half of the mixture into a gallon-sized zip top storage bag for marinade, and cover and refrigerate the other half to use later as the dressing.
For beef & salad: Place steak in bag with marinade, seal and refrigerate for 4 hours or up to overnight. Remove steak from marinade and preheat grill to medium-high. Rub Red Thai Curry onto both sides of steak then grill for about 5 min. per side for medium doneness. Transfer to a cutting board, tent with foil and let rest for 15 min. Slice steak against the grain into 1/4-inch thick pieces and toss with half of the reserved dressing. Prepare salad plates with a scoop of cooked noodles and a handful of greens then add a pile of sliced beef. Top with remaining garnishes to taste and serve with remaining dressing on the side.
