   1 1/4  pounds        fresh tuna steak, -- trimmed of skin                   
                        and any dark portions, cut into -- 1 1/4inch cubes    
     2-4                bay leaves                                             
       1  clove         garlic, -- crushed and peeled                         
     1/2  teaspoon      kosher salt                                           
       3  tablespoons   fresh lemon juice                                      
       1  tablespoon    olive oil                                              
                        Freshly ground black pepper to taste                   
                        Lemon wedges for garnish

Preparation:

In a bowl, cover bay leaves with water; let soak for 30 minutes. If using wooden skewers for the souvlaki, soak four 10inch skewers in water as well. With the side of a chef's knife, mash garlic with salt. Transfer to a small bowl and whisk in lemon juice, wine, oregano, oil and pepper. Measure out 3 tablespoons and reserve for basting. Place tuna in a shallow glass dish and pour the remaining marinade over it, turning to coat. Cover and marinate in the refrigerator for 20 to 30 minutes, turning often. Meanwhile, prepare a charcoal fire or preheat a gas grill. Thread the marinated tuna onto skewers, placing a soaked bay leaf between each piece of fish. Grill the souvlaki, covered, turning several times and basting the browned sides with the reserved marinade, until the tuna is opaque in the center, 8 to 12 minutes. Serve with lemon wedges.
