Mairi MacRitchie visits Islay and Lewis gathering tasty recipes to cater for those with special dietary requirements or hoping to cut down on meat. Suggestions include a spicy vegetarian shepherd's pie and a juicy aubergine and mozzarella bake. A young baker shows Mairi his recipe for a broccoli and stilton quiche packed with flavour and the presenter makes her own roasted vegetable tart with home-made basil pesto, and two bakers share recipes for gluten free cakes.
