1. Cut tuna into quarters lengthwise. Pour sesame oil over tuna; turn to coat evenly. Refrigerate 30 minutes. Mix black sesame seed, pepper and salt on large plate. Coat tuna with black sesame seed mixture, pressing firmly so mixture adheres to the tuna.
2. Heat oil in large skillet on high heat. Add tuna; sear 2 minutes per side. Remove from skillet; set aside to cool.
3. Slice tuna into 1/8-inch thick slices. Place 1 slice of tuna on each cucumber slice. Top each with a small dollop of Wasabi Citrus Aioli.
Tips
Test Kitchen Tip: Ahi tuna is also known as yellowfin tuna. Since the tuna is served rare on the inside, be sure to choose high quality sashimi-grade tuna.
