Remove tops from beets and reserve. Peel beets and remove root, then cut into bite size pieces. Peel carrots and cut into bite size pieces.
Toss beets and carrots with 1/2 tbsp of olive oil, garlic and salt and pepper. Spread on a lined rimmed baking sheet and place in the oven. Roast for 35 minutes, turning once about half way through.

Heat a sauté pan over medium heat and add remaining tsp of olive oil. Add the beet stems and greens to pan, then and apple cider vinegar. Sauté until tender. This should only take a minute or two. Remove from heat and allow to cool.
Allow the roasted beets and carrots at least 10 minutes to cool before assembling the salad.
