1) Coat an outdoor grill or stovetop grill pan with cooking spray and preheat to medium-high.
2) Season both sides of salmon with salt and black pepper. Grill salmon steaks 5 minutes per side for medium-rare. Arrange green beans on grill alongside salmon. Grill 10 minutes, until crisp-tender, turning frequently.
3) Meanwhile, in a blender, combine remaining ingredients and puree until smooth. Serve 4 of the salmon steaks with green beans on the side and ponzu sauce drizzled over top. Reserve remaining salmon steaks for another recipe. Serve with cellophane noodles.
