This rich soup is native to West Africa and comes from allrecipes.com. "Ground Egusi seeds give this soup a unique color and flavor. If you can't find Egusi seeds, you can substitute pumpkin seeds. Any combination of crab, shrimp and smoked fish can be used in place of the shrimp. Drained, smoked oysters and chicken can be used in place of the beef." You might even try collards or chopped cabbage instead of spinach.
