Derf, Thank you for another wonderful recipe! To cut fat and calories even more, I used Napa cabbage leaves that I just put into boiling water after I scooped the asparagus out,for a ten count, drained and cooled, then used as a wrap for the tuna mixture. It was delish! Next time I think I will leave the mayo out..don't think it will even need it. I did add a good pinch of curry powder that I mixed with the yogurt.
