     1/4  cup           to 1/2 c fresh lime juice
     1/4  cup           soy sauce
     1/2  cup           vegetable oil

Preparation:

Combine and blend all ingredients, except fish, in blender until smooth. Marinate fish for 30-40 minutes. Grill over medium hot coals until cooked through. Baste with the reserved marinade several times during cooking. Serve with lime wedges, avocado slices and pico de gallo. We have also used this same marinade on boneless, skinless chicken breasts. We marinate the chicken breasts for a couple hours though, and then barbeque them like we did the fish. From Cooking with Patsy Swendson, "Viva Fiesta"
