Caprese Orzo Salad

0 Cook the orzo according to package instructions, then drain, toss with one tablespoon olive oil, and let cool.
1 Add the orzo, chicken, spinach, cherry tomatoes, mozzarella, and basil to a large bowl and toss to combine.
2 Make the balsamic vinaigrette: add all of the vinaigrette ingredients to a mason jar, then secure the lid and shake the bottle vigorously for about 10 seconds, until combined.
3 If eating immediately, pour the vinaigrette over the salad and toss to combine. If prepping ahead for the week, leave the dressing in a separate container and pour over the salad when ready to eat.
