Preheat oven to 400°F (200°C). Dust a baking tray generously with flour or line with non stick baking paper
Mix together flour, salt, cheese, olives and sun dried tomatoes.
Gently stir in milk and oil until combined and you have a slightly sticky dough.
Turn out onto a floured surface and knead for 20 seconds and form into a ball.
Place the ball onto the floured tray. Flatten slightly.
Cut a cross into the top of the dough.
Bake for 40-45 minutes or until thoroughly cooked through. Check by inserting the blade of a knife into the damper. If uncooked dough is on the blade cook for 5 more minutes. There will be cheese sticking to the blade of the knife. That's ok.
Wrap in a tea towel to cool to retain moisture. Serve warm or cool.
