Guacamole Potato Salad

3 pounds red potatoes
2 T. salt
1 ripe avocado, peeled
2 t. grated lime zest, or juice of two limes
2 garlic cloves, crushed
1/2 C. chopped cilantro
2 T. mayonnaise
2 celery stalks, sliced

In large pot, boil the potatoes and salt then simmer about 20 minutes or until tender. Drain and cool. Meanwhile puree the avocado, lime zest and juice, garlic, cilantro, mayo and some salt in a food processor or blender until smooth. If too thick, add a little bit of hot water. Cut the potatoes into bite size chunks leaving the skins on and place in a large bowl with celery. Scrape in the dressing and gently stir together. Serve immediately or chill. Serves 8.
