Wild Arugula and Avocado Salad

• wild arugula
• cut avocado
• http://loxstockandbarrel.blogspot.com/2007/02/dijon-vinegrette.html (made with Champagne vinegar and walnut oil)
• salt
• ground white pepper

I used white pepper to accentuate the pepperiness of the arugula, because these two ingredients have a similar spiciness to me.
