Chop the bodies -> remove bones -> blend flesh in a blender -> store in large containers -> use thick bleach to dissolve bones in a secluded area -> anything you can't get rid of attach a weight and dump in ocean -> use small amounts of blended flesh (boiled) in cooking to avoid disease and food poisoning. I would recommend hiding the containers behind a false wall, under a floorboard, or just seal them into a wall.
Alternatively, you could travel to a wooded, secluded area away from civilization and burn the bodies in a bonfire. If anyone comes, tell them you had some old stuff in your home you wanted to burn and/or then kill them and out their body on the fire. If you choose this method, I would advise avoiding authorities through legal means, as this draws less suspicion and you are less likely to get caught transporting the bodies.
Remember throughout either of these you should always wear thick rubber gloves that you should then dispose of after each interaction with the bodiesβΊοΈ
