Make the dressing. Prepare the dressing by combining yogurt, oil, vinegar, mustard, bleu cheese, salt, and pepper in a mixing bowl; whisk together until thoroughly combined. Set aside.
Make the salad. Arrange the salad greens on a large plate. Arrange chicken, bacon, egg, tomatoes, avocado, and blue cheese on top of the salad greens.
Add the dressing. Drizzle the salad with the prepared dressing and serve.
Notes
Lettuce: Use crisp, fresh lettuce and ripe tomatoes and avocados.
Add protein: Grilled or roasted chicken, eggs, and bacon are common ingredients in a Cobb salad, but you can also try adding cooked salmon, beans, tofu, or even shrimp!
Dressing: I like to make my own homemade bleu cheese dressing to use in this Cobb salad, but if you'd like to use something not creamy, I suggest mixing up some lemon juice with olive oil and season it with salt and pepper.
Add-ins and swaps: While the traditional ingredients of a Cobb salad are amazing, you can also try adding other things to give the salad more variety. You can include diced bell peppers, sliced cucumbers, radishes, or diced vegetables.
Assemble the salad just before serving: To prevent the salad from becoming wilted or soggy, it is best to assemble the salad just before serving. This will also help to keep the ingredients fresh and vibrant.
