Got family over on Tuesday for a meal - it's very rare that I cook for more than just me, DH and DS and one of the people coming round is very judgey so I need to make something nice. Normally would go for something I can't screw up a roast, casserole or similar but its just too warm for anything like that at the moment. Please can someone suggest anything? Oh, and can't cost the earth to make, max budget is £15-20 to feed 5 adults and 1 toddler!
