DRESSING: Combine all dressing ingredients in a jar, shake well, and pop in the fridge until ready to use. Shake again before using. (Can make ahead of time--see Note 3.)
ORZO: Cook orzo in salted boiling water (2 tsp salt in 8 cups water) as per package instructions. Drain, rinse with cold water, and toss with 2 tbsp dressing.
ASSEMBLE: For immediate serving, mix orzo with all salad ingredients, add dressing to taste, adjust seasoning, and serve. If you want to enjoy salad throughout the week, store components separately and assemble as needed to prevent sogginess and avocado browning.
