Cut the chicken thighs into bite-size pieces and add them to the crockpot.
Season the chicken with garlic salt, garlic powder, black pepper, and Italian seasoning.
Add the minced garlic to the crockpot.
Mix the chicken well so all the pieces are evenly coated in the seasonings and garlic.
Pour the low carb pizza sauce over the chicken, covering it evenly.
Sprinkle the mozzarella cheese evenly over the pizza sauce.
Top the cheese with pepperoni.
Cover and cook on LOW for 4 to 6 hours, until the chicken is fully cooked and tender.
Serve warm and enjoy.
