The deep, satisfying flavor of beets adds sweetness to a pretty salad of baby spinach, tomato, and avocado, drizzled with a light dressing. This salad has been a huge hit with everyone, even my 8-year-old grandson.
Place beets into a large pot and cover with water; bring to a boil. Reduce heat to medium-low and simmer until tender when pierced with a fork, about 1 hour. Drain and cool until beets can be easily handled. Peel beets, cut into cubes, and place in a bowl; refrigerate until chilled, about 15 minutes.
Whisk lemon juice, olive oil, balsamic vinegar, mustard, salt, pepper, and garlic salt together in a large bowl until smooth. Add beets, tomatoes, onion, avocado, and feta cheese; toss. Top salad with spinach and toss.
