Ingredients

Fish Marinade:

1 cup seeded and chopped tomatoes (about 1/2 pound)

3 scallions, thinly sliced

2 fresh or pickled jalapeño chilies seeded and minced

2 tablespoons fresh lime juice

2 tablespoons white-wine vinegar

3 tablespoons olive oil

3 tablespoons fresh cilantro, chopped

1 1/2 pounds of firm fleshed white fish (striped bass, halibut, tilapia)

Rubios Sauce:

1/2 cup plain yogurt

1/2 cup mayonnaise

1/2 teaspoon cumin

1/2 teaspoon chopped fresh dill

1/4 teaspoon cayenne

juice of 1 lime

salt to taste

15 small corn tortillas

Fixings:

1 1/2 cups red cabbage, thinly chopped

2 avocados, sliced or 1 cup of your favorite guacamole

1 cup of fresh tomatoes, chopped or your favorite salsa

1 cup grated sharp cheddar cheese

1/2 cup cilantro, chopped

Preparation

In a bowl combine the ingredients for the marinade. Add the fish. Cover and refrigerate for at least an hour or overnight.

Make the Rubios sauce by whisking the ingredients together in a bowl. Cover and refrigerate. Can be made two days ahead.

Wrap groups of 5 corn tortillas in aluminum foil.

Place an oiled hinged fish grate onto a large plate. Transfer the fish from the marinade and place into the grate. (The plate underneath prevents the marinade from dripping). Prepare barbecue (medium-high heat). Grill the fish until the center is just opaque, about 5 minutes per side. While fish is cooking, place the foil-wrapped tortillas on the grill to warm.

Set up a buffet with all of the fixings, the tortillas and the fish.
