In 6 or 8 litre pot bring water, split peas, onion, yam, and celery to a boil. Reduce heat and simmer covered about 30 min. Add spinach, garlic and basil. Bring to boil again. Reduce heat and simmer 25-35 min. Note: I'm not sure where this recipe came from, but the original called for 3 Tbs. olive oil to be added to the water in the very beginning. The actual name is POPEYE'S SWEE'PEA WITH OLIVE OYL ...and it is said to contain all of Popeye's favorite sweet peas, yams ( " I yam what I yam"), olive oil and of course spinach. :)
