Rustic Tuscan Soup

This is my version of what the Olive Garden serves... My husband has stated several times that this is SOOO much better, it's not even funny.

Serves about 8 hungry people

1 Tbsp olive oil
1/2 lb thick-cut prosciutto, cut into small bits
4 cloves garlic, minced
2 lbs mild Italian sausage
5 lbs potatoes, small cubed
4 stalks celery, small diced
2 Tbsp Kosher Salt
1/2 gal water
2 cubes chicken bouillon
1 pint half and half
2 bunches Kale, de-veined and chopped

In a large stockpot, heat olive oil to medium high.
Add prosciutto and garlic and let cook over medium heat until meat begins to crackle
Add the sausage, breaking it up into small chunks
Cook until sausage is completely cooked through
Add potatoes, celery and salt
Add water and bouillon
Bring to a boil, and reduce to a quick simmer
Let cook until potatoes are just fork-tender
Add half and half and stir
Add kale and stir through
Cook another 5 minutes on medium heat

Serve with rustic bread.
