Great green goddess salad

For ➍
1 clove garlic
1 small anchovy*
½ handful lightly packed fresh parsley
2 medium scallions, white & green parts separated
½ ts dried tarragon
6 cl plain Greek yogurt
2 tbs mayonnaise
1 tbs white wine vinegar
½ ts salt
2 tbs olive oil
125 g baby spinach, washed & dried
1 medium cucumber, peeled & sliced
1 medium avocado, sliced

In the food processor, combine the garlic, anchovy (if using), parsley and the white parts of the scallions. Process to mince very finely. Scrape down and process again. Add the tarragon, yogurt, mayonnaise, vinegar and salt and process until smooth. With the machine running, drizzle in the olive oil until well mixed. Transfer to a pouring cup or jar; keeps for 4 days, tightly covered, in the refrigerator.
Spread the spinach on a platter or 4 small dinner plates. Cover with cucumber and avocado, and drizzle with dressing, then chop and sprinkle the scallion greens over the salads. Serve immediately. Top with cooked chicken or ham for a main course salad, or serve alongside grilled shrimp.

*The classic green goddess dressing has a hint of anchovy for umami, but if you want to leave it out, you can. Double the amounts in the dressing ingredients to make extra for salads throughout the week.
