Simple and bright, this salad is perfect on its own but it can become a filling and satisfying meal with the addition of grilled chicken or shrimp.
Cut segments from orange; squeeze 1 tablespoon juice from membranes into a large bowl. Into juice, whisk rice vinegar and olive oil; season with salt and pepper. Add spinach, orange segments, avocado, pepitas, and mint. Toss to combine.
