Preheat oven to 400°F. Wrap beets in foil, place on a baking sheet, and roast about 50 minutes or until tender. Let cool, peel, and slice into rounds or cubes
In a large serving bowl, combine the lettuce, roasted beets, diced avocados, roasted almonds, and orange segments
In a separate bowl or jar, whisk together the extra-virgin olive oil, balsamic vinegar, maple syrup, salt, and pepper to taste
Drizzle the dressing over the salad and gently toss to coat all the ingredients
