Line 2 large baking trays with non-stick baking paper.
Remove the sausages from their skins and place the sausagemeat into a large mixing bowl. Add the mustard, honey and parsley. Season generously with salt and freshly ground black pepper and mix well.
Unroll the pastry and cut it in half lengthways. Divide the sausagemeat into 2 equal-sized pieces and shape/roll into logs the same length of the pastry.
Place one log along the edge of one piece of pastry. Wrap the pastry around tightly to encase, ensuring there are no gaps. Pinch down the seam to seal. Place onto the prepared baking sheet seam-side down. Repeat with the remaining log and pastry. Cover and chill in the fridge for at least 30 minutes.
Meanwhile, preheat the oven to 200C Fan.
Using a sharp knife, slice each log into 6, creating 12 mini sausage rolls. Place well-spaced apart onto the prepared baking sheets. Brush with the beaten egg and sprinkle with sesame seeds.
Bake in the oven for about 25-30 minutes - or until the pastry is golden and puffed up and the sausage filling is cooked through.
Meanwhile, make the drizzle: pour the honey into a small saucepan and add the thyme leaves. Place over a gentle heat for about 1 minute, swirling every now and then. Set aside.
Next, mix together the mayonnaise and mustard (to taste) in a small bowl to make the mustard mayonnaise dip.
Once the sausage rolls are ready, drizzle over the thyme-infused honey. Carefully set onto a plate and serve with the mustard mayonnaise dip. Enjoy!
