A Christmas dinner tradition in my family accompanied with twice baked potatoes, rolls, green beans, fruit and great desserts! And the left overs are even better. Find roasts on sale?--have butcher give you the twine and place the seasonings on the roast, tie and freeze. Will marinate itself while you thaw it.
