My whole upbringing, Friday nights were spent sitting around a table, eating beautiful food and just sharing stories with at least 15 other people - Ronni Kahn

Research shows that out of every five shopping bags of produce we buy, we throw one away; we waste one

Secondly, only buy what you need. And of course, use your leftovers! I like to turn things like leftover roast vegetables into frittatas and soups. Be creative, experiment and have fun with food.

Growing up in an ethnic family, food was always central. In the Jewish religion, on Friday nights you bring in the Sabbath – for us it wasn’t so much a religious occasion but more a ritualistic one.
