Preheat oven to 190 degrees C. Grease muffin pan or line with patty cups.
In a large bowl, combine flour, baking powder, bicarb soda, salt, basil, oregano and sugar into large bowl; stir until well blended. Mix in sundried tomatoes, 1 1/2 cups of cheese and spring onions. In another bowl beat egg, whisk in buttermilk and stir until combined. Spoon batter into muffin pan until half full. Sprinkle remaining 1 cup cheese on top of muffins.
Bake in preheated oven for 15 to 20 minutes, until a toothpick inserted into centre of the muffin comes out clean.
