Slice the tuna in three thin paillards and marinate in the white wine, thyme, salt, and pepper. Lightly coat the radicchio wedges in salt, pepper and olive oil and grill until tender and slightly charred. Grill the pancetta until caramelized and crispy. Dice and set aside. Place radicchio in a bowl with the pancetta, green olives, balsamic and a drizzle of olive oil and toss to coat. Grill the lemon wedge. Grill the paillards of tuna on one side only until cooked to medium rare. Place radicchio salad in the center of the plate then add the tuna. Garnish with a drizzle of the marinade and top with the grilled lemon.
