Slimming World's hot dogs

These Slimming World’s hot dogs are really simple to make. The perfect guilt-free treat for the weekend taking only 45 mins to rustle up. Serve with American-style mustard and ketchup for a traditional finish. This recipe uses pork sausages but feel free to use other varieties to suit your taste buds.
Ingredients:
Low calorie cooking spray
2 onions, finely sliced
100ml boiling vegetable stock
4 Sainsbury’s Be Good to Yourself Extra Lean Cumberland Pork Sausages
4 lettuce leaves
4 x 60g wholemeal finger rolls, sliced open
Method:

Preheat the grill to medium.
Spray a non-stick frying pan with low calorie cooking spray, add the onions and cook over a low heat for 5 minutes. Add the stock and cook for a further 10 minutes or until tender. Drain off any liquid in the pan.
Meanwhile, grill the sausages for 15-20 minutes, turning halfway.
Put the lettuce leaves, sausages and onions into each roll and serve hot with chips (see above), tomato ketchup and American-style mustard.
