In a small bowl, whisk together the olive oil, lemon juice, orange juice, honey, harissa paste, and cumin until well combined.
Season the dressing with salt and pepper to taste.
Use the dressing to dress your salad, or store it in an airtight container in the refrigerator until ready to use. The dressing will keep in the refrigerator for up to a week.
To use the dressing, simply toss it with your choice of salad greens and any additional vegetables or toppings you desire. Some good options include chickpeas, raisins, and chopped pistachios. Enjoy!
