This beautiful salad represents a harmonic convergence of tastes. The spiciness of some of the greens in a spring mix is balanced by the avocado’s creamy, healthy fat, while the sweetness of the roasted beets cuts the acidic nature of the citrus dressing.If the beets vary in size, wrap them accordingly so you can remove the package of smaller ones when tender, leaving the larger ones in the oven until they are tender.
