Add the cubed yellow potatoes to your crockpot and spray them lightly with olive oil.
Season the potatoes with garlic salt, black pepper, garlic powder, onion powder, paprika, and Tony's Cajun Kick Seasoning.
Add the washed green beans, diced onion, and sliced Andouille sausage on top of the seasoned potatoes.
Add the stick of butter, sprinkle on a little more Tony's Cajun Kick Seasoning, then add the packet of onion soup mix and the minced garlic.
Cover and cook on HIGH for 4 hours, or until the potatoes are fork tender.
Give everything a really good mix so the melted butter, garlic, onion soup mix, and seasonings coat all the potatoes, green beans, and sausage.
Serve hot and enjoy.
