Preheat the oven to 180°C.
Sift the flours into a large bowl (adding in any flakes from wholemeal flour) with 1 teaspoon of salt. Rub in butter until mixture resembles fine breadcrumbs, then stir in tasty cheese and oregano.
In a separate bowl, combine milk with 1/4 cup (60ml) water. Make a well in the centre of flour and stir in three-quarters of the milk mixture. Add remaining liquid a little at a time until mixture just comes together. Turn out onto a lightly floured surface and knead gently for 1 minute.
- Shape into a round loaf and place on a greased baking tray. Brush top with milk and sprinkle with parmesan. Bake for 30 minutes or until loaf sounds hollow when tapped. Serve warm
