Super-easy and yummy green bean salad

This has got to be one the yummiest tomato and green been salad i have ever had! And it's so easy to make! The magic ingredient? I used roasted pecan nuts this time...they really give a unique flavour to the salad. And as usual, parmesan shavings add to the magic. 

So, to get started, you need for 4 servings:

400 gms green beans

100 gms cherry tomatoes

50 gms roasted pecan nuts

2 tbsps olive oil

1 tbsp vinegar

2 tsps old-style mustard (whole-grain)

parmesan shavings

salt

Trim the beans and boil until tender. Drain and run under cold water. Halve the tomatoes and crush the pecans coarsely. Carefully mix all three together in a big bowl. 

Make the dressing by whisking the vinegar and mustard into the olive oil. Add salt if desired. 

Gently toss the bean salad with the dressing and serve garnished with parmesan shavings.
