In a large saucepan, heat olive oil over medium-high heat. Add onion; saute, stirring frequently, until it is lightly golden, 2 to 3 minutes.
Add olives, garlic, jalapeno, lime juice, oregano, and orange zest; cook 1 minute. Add wine; continue cooking until it is reduced by half, 1 1/2 to 2 minutes.
Add tomato, clam juice, the water, and chicken broth; bring to a boil. Reduce heat to medium, and add seafood. Cover, and simmer until snapper and scallops are opaque and clams have opened, about 12 minutes. (Discard any clams that do not open.) Serve hot, ladled into soup bowls. Garnish with parsley.
Very yummy with some alterations. 1. The broth is very light. I intensified it by reducing 1-1/2 cups of chicken broth to 1 cup. I added some small pastina to make it just a little heartier. I increased the clams and added a few medium shrimp which made the recipe fit for 3. The clams need to cook longer than everything else so put them in the simmering broth first for 5 minutes or the other seafood will overcook. With those alterations this was really good with some french bread.
