Thinly slice the snap peas (or celery). Chop the broccoli into fine florets (you will have about 1 1/2 cups). Place in a large serving bowl.
To the bowl, add the lettuce, arugula, cucumber, green onion, and half of the avocado. Top with several big spoonfuls of dressing. Very gently toss to combine (I find clean hands work best for this). Everything should have a light coating of fressing, and the avocado will break down a bit to make the salad even creamier. Taste and adjust seasoning as desired. Scatter the second half of the avocado over the top. Serve immediately with extra dressing on the side.
For the Dressing:
In a food processor, place the Greek yogurt, lemon juice, oil, mixed herbs, garlic, Worcestershire, salt, pepper, and onion powder.
Blend until smooth and only tiny specks of herbs remain. Taste and adjust salt and pepper as desired. Enjoy on salads, as a dip, over pasta, with meat or fish, and more!
Notes
*To keep stronger herbs from over-powering the dressing, use a max of 1 cup parsley, 1/4 cup chives, 1/4 cup mint, and/or 2 tablespoons tarragon. Parsley, dill, tarragon, and chives is my favorite combo.
