Recipe from The Riverfront Times' Recipes 1997 and states it was submitted by Chef Gregory Mosberger from te Carriage House Restaurant. He recommends serving the tuna atop a salad of tossed greens, nicoise olives, steamed green beans and hard boiled egg (similar to a Nicoise salad). Recipe is for 6 tuna steaks, so unless you are serving this at a party, you'll want to decrease the marinade and mayo accordingly. You also need to plan ahead for marinade time. NOTE: I made this today and the marinade is absolutely fabulous to say the least (I marinated the tuna for about 2.5 hours and it was so flavorful). I served mine atop some broccoli slaw that I simmered in chicken broth.
