Cut pork into 2-inch pieces. Season with salt and pepper.
Heat a large non-stick skillet on high heat; when hot lightly spray the pan with oil and brown the pork over medium heat on all sides, about 3 - 4 minutes total.
Sprinkle 1 tbsp of flour over pork and stir to cook 30 seconds, sprinkle remaining flour over pork and cook an additional 30 seconds.
Add browned pork to the crock pot, along with the remaining ingredients.
Cook on LOW for 6 to 8 hours or HIGH for 4 hours.
When done, adjust salt and pepper to taste if needed.
