Pasta and Pesto

Pasta and Pesto is mine and Tabi's favourite but there is only so much of it we can eat - Mummy doesn't appreciate just how much pasta expands when it is cooked; We have about 1KG of cooked pasta now in the fridge following this evenings meal- the funny things is every time Mummy cooks it she says "we need a bigger saucepan" - I am not convinced!
