Step 1: Prepare the miso vinaigrette by whisking together all ingredients except the oil. Gradually add the oil while whisking until the vinaigrette is well combined.
Step 2: For the crispy shallots, toss shallots with flour in a bowl until fully coated. Season with salt and pepper. Fry in avocado oil over medium-high heat until crispy and caramelized, about 7 to 8 minutes.
Step 3: Assemble the salad by tossing kale, avocado, mozzarella, cherry tomatoes, scallions, and chicken with your preferred amount of vinaigrette. Top with fried shallots and serve. Enjoy your revamped Cobb salad!
