Combine the oil, garlic, anchovy fillets, and 1/4 teaspoon pepper in a small saucepan over low heat. Cook for 5 minutes or until garlic begins to sizzle; remove from heat. Set aside.Preheat a grill pan over high heat. Lightly brush the tuna with cooking spray. Sprinkle with salt and the remaining 1/4 teaspoon pepper. Transfer to the skillet; cook for 2 minutes on each side or until just cooked through. Remove from the mold.Combine 1 teaspoon butter mixture and broccoli; toss to combine. Add to the skillet; cook for 6 minutes or until tender, turning occasionally. Arrange 1 tuna steak and 4 ounces of broccoli on each of 4 plates. Drizzle each serving with about 1 1/2 tablespoons of the butter mixture. Serve with lemon wedges.
