*I use Panera Bread Poppyseed Dressing, found in your grocer's produce department. TO MAKE VEGAN: Omit the feta cheese and use a vegan mayo. TO MAKE WHOLE30: Omit the feta cheese and use a Whole30 compliant mayo. PUMP IT UP: Feel free to add bacon, rotisserie chicken, quinoa or chickpeas to this salad to make it a complete meal.
