This is a vegetarian, savoury pancake but great for everyone to enjoy. Serve in the winter, with baked beans, or a salad if you don't feel the cold!
Pancakes are generally made using plain flour but self raising is fine if this is all you have. Remember, the more finely chopped the filling ingredients, the quicker they will cook through, and it works quite well to prepare all the veg in a food processor, if you have one.
Instead of an apple you could use a pear or indeed the flesh of a sharp orange, finely chopped.
