Sinon stub mongoose save to resolve the object which called save

I have the following code:

const newImage = new Image(...);
newImage.save().then(image => {...})

Is there a way to stub the save method for Image to resolve the object which called it? ie. I want image in the then clause to just be the same as newImage

Something like sinon.stub(Image.prototype, 'save').resolves(theCallingObject);

Is this possible? Any help is appreciated. Thanks!
