I think its fine if the sauce doesnt have the mince in it. If it does then I would say no coz I have always been told that you shouldnt refreeze anything that has been previously frozen!!
You shouldnt refreeze anything thats thawed out and is being refrozen in its original state. If though you defrost it and cook it you can refreeze it in its 'new' state
