Make the dressing: Whisk the tamari, rice vinegar, maple syrup, and toasted sesame oil in a medium bowl.
Option 1 (For Meal-Prep Salad Jars): To make 4 (16-ounce) mason jars: Add one-fourth of the dressing to each jar. Then add ½ cup cucumber, ½ cup celery, ½ cup green peas, ½ cup edamame, ½ cup quinoa, ½ cup spinach, 2 tablespoons cilantro, 2 tablespoons scallion, and 2 teaspoons sesame seeds to each jar. Refrigerate for up to 4 days. Shake before serving. Add fresh lime juice to taste. Or make 2 (32-ounce) jars and double the ingredients for a high-protein, more satisfying main dish.
Option 2: Transfer the cucumber, celery, green peas, edamame, quinoa, spinach, cilantro, scallion, and sesame seeds to a large bowl. Add the dressing and mix to combine.
Notes
Usefrozen shelled edamame for this edamame salad. They do not require further cooking. Simply thaw them in a sieve under running warm water and dry between the layers of a kitchen or paper towel. Alternatively, thaw them overnight in the refrigerator.
For the salad jars, change the order of ingredients as desired, but keep the leafy greens and fresh herbs on top. I enjoy the cucumbers pickled, so I place them at the bottom.
Storage: Refrigerate any remaining salad in an airtight container for up to 4 days. The mason jar salads remain fresh in the refrigerator for up to 4 days.
