Preheat oven to 170 degrees C (Gas mark 5).

In a large bowl, combine oats, sunflower seeds, almonds, and crushed hazelnuts.

In a separate bowl, mix honey, sunflower oil, water, vanilla extract, and cinnamon.

Microwave the liquid mixture for about a minute to ensure thorough mixing.

Pour the liquid mixture over the dry ingredients and stir well to coat evenly.

Spread the granola mixture on a large baking tray in a thin layer.

Bake in the preheated oven for 30-40 minutes, stirring and turning occasionally to ensure even browning.

Once the granola is evenly browned, turn off the oven and leave the door ajar to allow the granola to fully dry and crisp up.

Remove from the oven and let the granola cool completely.

Once cooled, add the finely chopped apricots and mix well.

Store the granola in an airtight container at room temperature.
