Frozen sourdough bread. 
Any type of sourdough bread:
White Sourdough bread 
Wholemeal sourdough bread 
Multi-seed sourdough bread 
Or
Any flavoured sourdough (Cranberry cashew,  fig walnut et.)
To defrost a sourdough bread, follow these steps:
Leave the bread at room temperature for a few hours or until it is completely thawed. Do not use a microwave to defrost the bread, as this can cause it to become tough and chewy.
Once the bread is thawed, preheat your oven to 350°F (175°C). Place the bread directly on the oven rack and bake for 10-15 minutes, or until it is heated through and the crust is crisp.
