For Feast of Seven Fishes, you can knock out three fishes with this one dish! Unlike tomato-y options like bouillabaisse, cioppino or even fra diavolo, this light and bright seafood stew is flavored with jalapeno, cilantro, garlic, and fennel. The flavorful broth comes together quickly thanks to shrimp shells (because we know no one is out there making fish stock on the regular).
