I cheat by making the dough in a breadmaking
Ingredients
500g bread flour
5 eggs, boiled and peeled
5 slices parma or serano ham
200g grated cheese ( any tasty oddments)
Handful of fresh basil
I then add whatever I have available eg
Handful of black olives
sundried tomatoes
Pesto
Method
After proving knock back and roll into a rectangle approx 50cm x 20cm
Along the centre arrange all the filling ingredients
Pull one side of the dough up and over to create a cannelloni shape , then pull the ends round and pinch them together to form a doughnut shape.
Transfer to a floured baking sheet and leave to prove for 15 mins
sprinkle with flour and bake in a preheated oven 180 degrees C for 35 mins until golden
Cool on a wire rack before wrapping in a cloth ready to transport to your picnic....hopefully it will still be slightly warm when you get to eat it .
