Neven's Irish Food trails, 8.30pm, RTÉ One

This week’s Food Trail begins in the spectacular Comeragh Mountains, Co. Waterford where Neven meets Willie Drohan of Comeragh Mountain Lamb. Neven heads out into the mountains to see the herd of Scotch Blackface sheep roaming, and learns how living outdoors in the mountains gives the lamb a unique sweet flavour. But just how many cuts of meat can you get from one lamb? Neven also heads to Forest Avenue Restaurant in Dublin where Head Chef John Wyer guides him through the butchering process, and shows how even the less popular cuts can be used to create delicious recipes.

Grow, Cook, Eat, 7.30pm, RTÉ One

The humble but delicious tomato is the subject of tonight's show as presenter Michael Kelly visits Grantstown Nurseries in Ballygunner, Co Waterford, to learn about tomato growing on a commercial scale. Unfortunately, most of the imported supermarket tomatoes we buy taste of absolutely nothing at all. It is not until you grow your own that you realise this, contends Michael. Also tonight, Jack Kirwan, owner of the Sprout chain of restaurants in Dublin, takes over the Grow Cook Eat café this week and prepares a Garden Tomato Salsa and Tomato Pesto.
