If using bacon, cook and crumble. I cook it in the oven, usually.
Melt butter in a heavy bottom dutch oven over medium heat. Add the grits and cook for 1-2 minutes.
Add the next 8 ingredients and cook for about 5 minutes. Then add the chicken broth, cover and cook over medium-low heat for 20-25 minutes or until veggies are tender.
Add half & half. Heat through and remove from heat.
