1/2 yellow onion, diced small

Add onion and mint to cauliflower mixture; cook and stir until heated through, about 3 minutes.
Whisk olive oil, 3 tablespoons reserved lemon juice, salt, and pepper together in a bowl. Pour lemon juice mixture over cauliflower mixture and toss to coat. Season with salt and black pepper to taste.
