To make Salmon: Preheat the grill(or broiler). Leave the skin on the salmon, if desired. Place the barbecue sauce, vinegar, scallions, and ginger in a blender and mix. Start grilling the salmon to the desired doneness(3-6 minutes each side) and baste with barbecue sauce mixture as you are grilling(or broiling). If grilling with skin, grill skin side down until the skin is crispy, then turn over and continue basting with barbecue sauce mixture.
To make the Vegetables:.
Take out the hard bottom center of the greens. Slice greens thinly. Heat a saucepan over high heat, add oil and saute cabbage, radicchio, and mushrooms quickly(about 3-4 minutes). They should remain crisp. Before taking the veggies out of the pan, deglaze with the white wine or sake(by adding wine to bottom of pan, stirring and scraping bottom). Add salt and pepper.
To make the Chinese Mustard Sauce:.
Put mayonnaise, mustard powder, mustard, vinegar, scallions, and salt and pepper to taste in a blender and mix.
To Plate:.
Place the sauteed vegetables in the center of each plate. Place five or six dots of Chinese Mustard Sauce around the veggies. Put the salmon on top of the veggies. Sprinkle the plates with chopped scallions. Enjoy!
