In a large mason jar, whisk together all of the ingredients for the dairy-free ranch dressing. Cover and refrigerate for up to 3 days.
When you are ready to use the dressing, shake the jar or use a spoon to stir the ingredients up, and serve with the salad.
Make the Christmas Wreath Salad
Choose a large round serving platter. Place the bowl of salad dressing in the middle. Place the star bowl of tomatoes at the top middle space. Or, alternatively, place the tomatoes in the form of a ribbon at the top. Start to layer mixed greens in the empty space around the bowl of dressing. Then layer on the tomatoes and cucumbers. Add in any other vegetables, nuts, or cheeses you would like to add.
Notes
Preparation: If you have great airtight containers, you can make this salad a couple of days ahead of time. If not, it's best to prepare it no earlier than a few hours before serving so all the prepped veggies stay fresh.
