Add the flour, nutritional yeast, spices, baking powder and salt into a bowl, mixing to combine.
Make a well in the centre and add the milk and mustard, stirring until a batter forms.
Heat the oil in a shallow frying pan, over a medium heat.
Spoon a ladle of the batter into the pan, swirling the pan in a circular motion, so it spreads evenly across the base .
Cook for 3-4 minutes until golden brown on the bottom.
Add the filling to the middle of the batter, then fold in half over the filling using a spatula.
Serve immediately, with a side of salad or roast veggies as desired, drizzled with a few tablespoons of the creamy garlic sauce. Store the rest in a jar for later use.
Sprinkle over fresh micro herbs for extra flavour.
