I am aware this mind sound disgusting but it is just an idea.....my H cooked beef mince with gravy yesterday, he is the only one who eats it and he made a quite big batche. And I KNOW he won't eat it again, so as usual it will go from the fridge to the freezer and than eventually to the bin. I am wondering if I can wash it out and make a lovely brand new tomatoe sauce with it and than make a sheperds pie??
