Place bacon rashers under a hot pre-heated grill and cook for 2-3 minutes each side until crispy. When cooled slightly cut rashers into 3. Lightly cook green beans in boiling water until just tender, leave to cool slightly.
Place in a large bowl the bacon pieces, green beans, drained mixed beans, lentils, fresh herbs and cheese, toss well together.
Place ingredients for dressing in a jar with a lid and shake well to mix together.
Drizzle dressing over salad and serve.
