Cook cauliflower according to package directions. Meanwhile, heat a large sauté pan over medium-high heat.
Prepare the ingredients for the salad and add to a large mixing bowl.
Transfer the cauliflower to the hot pan to get rid of the excess moisture, stirring occasionally, for 5–10 minutes. Set aside to cool.
Combine the dressing ingredients in a small bowl, except for the oil.
Drizzle the oil in slowly while whisking vigorously.
Toss the salad ingredients together. Add dressing and toss to coat.
Serve immediately or chill for later, tossing just before serving.
