Cut and boil potatoes. Peel if you like, but I always leave the peel on.
Once potatoes softened, strain from water and put in crock pot. Save 2 cups of potato water.
Add flour, butter, milk, sugar, & cheese to crock pot & stir.
Find meat in fridge. I usually use chopped leftover brisket or breakfast sausage or baked ham. If you don't have these then buy 1 pkg cooked chopped ham & use that. I don't use an exact measurement, it depends on how meaty you want your soup.
Chop & add meat to crock pot & stir.
Sprinkle crushed red pepper & black pepper to taste.
Cover crock pot & cook either on low for 6-8 hrs or high for 3-4 hrs - until cheese is melted through. Check & stir occasionally until done.
If soup is too thick, add saved potato water until it is to your preference.
