Take the part baked rolls out of the packaging and place on a chopping board. Using a sharp knife, carefully cut out an oblong hole from the top of the rolls. Scoop out the bread, ensuring you don’t pierce the bottom of the rolls. Place the rolls on a baking tray.
Use a grater to grate approx 2 tbsp of breadcrumbs from the pieces you chopped out. Discard the rest of the scooped out bread (or grate all of it, and freeze the leftover breadcrumbs).
In a bowl, mix together the cheddar, mozzarella, cream, salt, pepper, sun dried tomatoes and spinach.
Spoon this mixture into the bread. Sprinkle on the reserved breadcrumbs.
Place in the oven and bake for 10 minutes, until the top is golden brown.
Take out of the oven and serve sprinkled with parsley.
