Easy recipe that was ready in about ten minutes with prep time. I used frozen tuna fillets from Publix and I was pleasantly surprised. You can get two fillets this week for under $7 dollars which is a steal. Marinated in soy sauce and lemon juice. I didn't get too crazy with the marinade since I was serving this dish with the Horseradish Dijon. Grill over medium med for 2 minutes on each side. Plate and drizzle with Kraft Horseradish Dijon Mayo. Garnished with sliced leeks.
