Hearty Split Pea Soup

I usually make my MIL's fabulous split pea soup, that starts with a ham bone. However I had some ham left over from a boneless ham and I came across this recipe that I could use it in, so I gave it a try. 
This recipe is a keeper and so super easy!!! 

1 [16 oz.] pkg.dried split peas, rinsed and drained
8 cups water
2 medium potatoes, cubed
2 large onions,chopped
2 medium carrots, chopped
2 cups cubed cooked corned beef or ham
1/2 cup chopped celery
5 tsps. chicken bouillon granules
1 tsp. dried marjoram
1 tsp. poultry seasoning
1 tsp. rubbed sage
1 tsp pepper
1/2 tsp. dried basil

In a Dutch oven, combine all of the ingredients and bring to a boil. Reduce heat, cover and simmer for 1 1/4 to 1 1/2 hours until peas are tender.
