In a large bowl, beat the vinegar (and sugar if required) with garlic, salt and pepper until salt has dissolved. In small additions, add the olive oil while whisking constantly. Taste and add more seasoning if required.

In a bowl, add the salad mix and assortment of salad additions. Pour vinaigrette over the salad and toss to mix. Top the salad with blue cheese.
