My sister brought round a rib of beef she'd got in Aldi half-price, and as she and her partner are off on holiday, she's given it to me. But I'm a minimum wage earner, living off chicken, mince and occasionally pork, and I have never cooked beef. I don't want to ruin it, as even half-price it was expensive!! I've got friends coming for dinner tomorrow and would be ever so grateful for some cooking suggestions. Thanks in advance.
