In a skillet, over medium-high add the ground beef. Cook it without moving for 3-5 minutes in its own fat, until nicely seared. Start breaking it with a spoon, season with salt and pepper and cook until no longer pink.
Stir in the celery, onions, bell pepper and garlic, cook for another 3-5 minutes.
Add the mixture to the slow cooker, add the rest of the ingredients and the SPICES.
Cover and cook on LOW for 6 to 8 hours or on HIGH for 4 to 6 hours. Keep the lid on and refrain from opening.
Garnish with favorite toppings and serve warm.
