Preheat grill to 350 degrees.
In a medium bowl, whisk together 2 tablespoons olive oil and 1 tablespoon balsamic vinegar.
Place fig halves into the bowl with the balsamic mixture. Toss very gently to coat.
Place figs cut-side-down onto preheated grill. Grill for 2 to 3 minutes, until grill marks appear. Turn over using tongs and brush with balsamic vinegar and continue grilling for an additional 2 to 3 minutes.
Remove figs to a platter and brush each fig on the cut side with more balsamic vinegar and drizzle lightly with truffle honey.
In a separate bowl, place 8 cups baby salad greens and drizzle and toss with desired amount of dressing.
To serve, place dressed salad onto plates and top with grilled figs. Drizzle lightly with additional balsamic vinegar and garnish with toasted walnuts and crumbled or shaved cheese. Serve immediately.
Dressing: Combine all ingredients in a jar with a tight fitting lid and shake well until well combined.
