Leftover Prime Rib Sub

posted in: Recipes 0

I’ve always had an issue with getting the exact amount of prime rib for dinner. If I’m cooking for just the fam, I tend to overdo it. If we’re hosting, it’s all over the place. I’ll buy what I think is too much and I’ll be short, then there’s times when I think I don’t buy enough and I have leftovers. My standard now is to go with more than I think I’ll ever need. That way I can enjoy a leftover prime rib sub. This sub includes melt cheese and a horseradish sauce over a soft roll.
