1After chopping all vegetables, saute with olive oil until translucent, adding little salt.
In separate pan, scramble sausage till done, pour out onto paper towels over brown paper bag and let drain. To get even more grease out press with paper towels. When cool add it to the vegetables. This can sit overnight if you'd like or continue with cooking.
2Place water and rest of salt in two-quart pot and bring to a boil. Add grits and cook until done, stirring frequently. Then add to sausage and vegetables. Mix well and pour into large casserole dish.
3Spread cream of celery soup over top of casserole and sprinkle cheese evenly over top. Bake at 350 degrees for about 30 minutes. Check to make sure not getting too brown. Seems like a lot to do, but it is delicious. Not only good for breakfast, but dinner also. I usually serve with cheese muffins.
