In a small bowl whisk together tahini, honey and lemon juice. While continuing to whisk together, add oil, in a slow and steady drizzle until fully incorporated. Season with salt and pepper. Set aside.
Pre-heat broiler to high. Place salmon and corn onto a baking sheet and drizzle with oil. Season generously with salt and pepper.
Place under broiler for 2 minutes, until corn has charred on one side. Turn corn and broil for an additional 2 minutes. Remove corn and broil salmon for an additional 5 to 7 minutes or until salmon has just cooked through. Remove from heat, slice kernels from cob and shred salmon fillet.
To assemble: Pour ¼ cup vinaigrette into the bottom of a mixing bowl and toss top with romaine. Toss together until romaine is evenly coated. Transfer romaine onto a large platter. Top dressed romaine with salmon, corn, chopped avocados, sliced peach, shredded cheese, and sprinkle entire salad with green onion. Drizzle more vinaigrette over salad, lightly season with salt and pepper and serve.
