To make the dough, place water, yeast, sugar and EVOO into the Thermomix bowl and warm 2 min/37/speed 2. Add remaining dough ingredients. Combine 6 sec/speed 6. Knead 3 min/Interval.
Tip dough out onto a floured silpat mat. Wrap up and allow to rise until doubled in size.
Meanwhile, line the base of a round spring form tin. and butter the sides. Preheat the oven to 200°C.
Place cheeses into the Thermomix bowl and mill 10 sec/speed 10. Set aside.
Divide dough into even balls, the same quantity as you have sausages.
Flatten each ball of dough and roll out slightly, so it is big enough to wrap around the sausage.
Spread plenty of tomato sauce and mustard onto the dough, sprinkle with cheese. Place a sausage on top and roll up.
Arrange all your wrapped up sausages standing up in the tin. Cover and allow to rise.
Bake for 25 minutes. Serve with more sauce and mustard to taste!
