In a large pot, heat the oil and saute the onion and garlic. Add the remaining ingredients and simmer until done, about 35 minutes.

The acid in the lime "juice cooks" the seafood. The ratio should be at least 3/4 cup lime juice to one pound of raw seafood such as scallops or shrimp. Season with salt, pepper, and your favorite spice, serve over salad.
