In a large bowl, gently combine the grated beets, grated jicama, sliced avocado, orange pieces, and chopped cilantro.
In a small bowl or jar, whisk together the thawed orange juice concentrate, lime juice, ground cumin, and ground coriander.
While whisking continuously, slowly drizzle in the olive oil until the dressing is emulsified.
Pour the dressing over the beet and jicama mixture and toss gently to coat everything evenly.
Season with salt and pepper to your liking.
Divide the salad among serving plates and sprinkle generously with toasted pumpkin seeds before serving.
Add a spicy kick by finely dicing half a jalapeño (seeds removed) and adding it to the salad with the other vegetables.
