Bring salted water to the boil and cook the green peas, carrots and pumpkin separately. Add the cooked vegetables to the Bolognese sauce and season to taste.
Prepare the pie
Roll out the pâte sablée to 2-3 mm thickness, then cut two discs, a large one for the mould and a smaller one for the top.
Cut scary faces in the pastry tops and keep in the fridge.
Gently grease the individual tart moulds and place the larger discs into it before pricking the bottoms of the tarts with a fork.
Fill the tarts with the filling and brush the egg wash around the side of the tart.
Close the pie with the smaller ‘Halloween faces’ and press with your fingers to close well.
Keep in the refrigerator for 30 minutes. Brush more egg wash on top and bake for 30 minutes at 180°C.
