Preheat oven to 400. Place the beets in a bowl with the 2 tablespoons of the oil, the sugar, the fennel seeds and salt and pepper, and toss to combine. Place on a baking tray lined with parchment paper and roast for 10 minutes.
Add the carrots, garlic and chickpeas to the tray and roast for 20 more minutes. Place the vegetables and chickpeas in a bowl with the spinach. Combine the remaining oil and lemon juice in a jar and shake to combine. Drizzle over the salad. Serve with the labne.
Notes
You can use all one color beets if that's all you can find. If you can find thin, whole young carrots, use those instead of the "baby" carrots that are bagged. Those really aren't baby carrots, they are larger carrots cut to size. If you can't find labne, you can make your own by placing yogurt in a cheesecloth and letting it drain over a bowl in the fridge for a few hours or overnight. It's also good with feta cheese crumbled on top.
