Put the flour, salt, bicarbonate of soda, garlic granules, oregano, salt and pepper in a mixing bowl. Whisk together so that everything is evenly distributed.
Add the crispy onions and the grated cheese. Whisk again.
Make a well in the centre. Pour the yoghurt and lemon juice into the well. Mix well until all the flour is incorporated and it starts to clump.

Transfer your dough to a nonstick baking sheet.
Press a cross into the top with a wooden spoon. This helps the dough rise and gives the loaf a classic soda bread shape.
