Ahi Tuna Club

For those who love seared tuna, this is the perfect sandwich for you. Overcooking fresh tuna results in a dry texture.

1. Dip the tuna in sesame seeds, and in a hot skillet sprayed with vegetable oil, sear the tuna for about 2 minutes per side, depending upon the thickness. The tuna will continue to cook after searing. Remove from the heat, cool, then thinly slice.
2. Toast the bread slices.
3. Combine the guacamole, mayonnaise, wasabi and cilantro. Spread over the bread slices. Place the tomato slices, prosciutto and spinach leaves on 4 slices of the bread. Add the tuna. Place the other bread slices overtop and serve.
