Place mushrooms in large zip-top baggy containing marinade ingredients. Shake and let sit for 1 hour.

Add wine and sugar. Cook until liquid is evaporated, stirring. Remove from heat to cool then stir cooked red onions into mayonnaise. Set aside.

Place mushrooms on paper towels to drain. Stir together cream cheese, stilton, Tabasco sauce and chives in a small bowl. Stir in crab meat then spread mixture into cavities of mushrooms. Set aside.

In a large bowl combine ground chuck, chopped yellow and red onion, egg, mustard, ½ teaspoon salt, and pepper. Shape into 6 patties to fit diameter of buns. Press quarter size indention in center. Sprinkle patties with remaining kosher salt and cook. Oil grill rack and cook burgers, covered, for 5-6 minutes per side for medium doneness. Cook stuffed mushrooms on outer edges of grill, along with burgers, removing once mushrooms are softened (about 5-6 minutes).

Lightly toast rolls, cut side down, on outer edges of grill during last few minutes of cooking. Spread cut sides of bread with mayo mixture. Place burgers on bottom buns. Top with stuffed mushroom then romaine lettuce then diced tomatoes. Replace with top bun.
