In a small blender, combine all ingredients except poppy seeds. Season to taste (I recommend 1/2 tsp salt). Blend until smooth. Then, using a spoon, stir in the poppy seeds (do not blend). Taste and adjust if needed.Transfer to a mason jar and refrigerate until ready to use. Shake well before using.
In a large bowl or on two salad platters, arrange the greens and toppings evenly. Drizzle with dressing gradually, adjusting to your taste. Gently toss and serve immediately. If you plan to store any leftovers, don’t add dressing, cheese, or avocado as dressed salad doesn’t store well.
Notes
Storage: Store leftover dressing in an airtight container in the fridge for up to a week. Shake or stir before using.
