Cook the Quinoa: In a small saucepan, combine the red quinoa and 1 cup / 240 ml of water.
Bring to a simmer, then cover, reduce heat, and cook for about 15 minutes, or until the water is absorbed.
Remove from heat and let it stand, covered, for 5 minutes.
Prepare the Salad Base: While the quinoa cooks, combine the diced jicama, red onion, black olives, cilantro, black beans, avocado, watermelon, and jalapeño in a large serving bowl.
Make the Vinaigrette: In a separate small bowl, whisk together the lime juice, avocado oil, white balsamic vinegar, honey (or syrup), ground cumin, sea salt, and black pepper until well combined.
Combine and Serve: Fluff the cooked quinoa with a fork and add it to the large bowl with the other salad .
Pour the vinaigrette over everything and toss gently to combine.
Serve immediately for the best texture.
Let the quinoa cool completely before adding it to the salad to prevent the other from wilting or the avocado from browning too quickly.
