Creamy Grilled Potato and Mushroom Salad

A great accompaniment to any BBQ dinner!  I love baby spinach and it works wonderfully in this salad!

2 lb (1kg) baby potatoes, halved
500g button mushrooms, trimmed
1/2 cup Diana Sauce, Original Flavour (or your favourite BBQ sauce)
2 tbsp vegetable oil
1/2 tsp each salt and pepper
1/2 cup light mayonnaise
2 tbsp chopped fresh coriander or parsley
1 red pepper, chopped
3 green onions, chopped
3 cups baby spinach leaves

1. Cook the potatoes in a large pot of boiling salted water for 10 minutes or just until fork tender.  Drain and rinse under cold, running water.  Transfer to a large bowl.  Add the mushrooms.
2. Preheat the grill to medium high.  Stir 2 tbsp of the sauce with the vegetable oil.  Gently toss the potatoes and mushrooms with the oil mixture, salt and pepper.  Transfer to a grilling basket or line the grate with perforated grilling foil.  Grill for 20 minutes, turning often until well marked.  Cool to room temperature.
3. Stir the remaining sauce with the mayonnaise and coriander.  Toss the potatoes, mushrooms, red pepper, onions and spinach with the mayonnaise mixture.  Serve at room temperature or cool.   Makes 10 to 12 servings.
