Preheat oven to 425 degrees.
Cut up your sweet potatoes in bite size chucks (about 1/2 inch thick) and arrange on a baking sheet. Drizzle olive oil and maple syrup over potatoes so they're coated. Sprinkle cumin, garlic salt, and red pepper flakes over potatoes. Using your hands or tongs, move sweet potatoes around so all sides have some coating. You can also do this step in a bowl first - but why dirty a dish if you don't need to?!
Bake both sweet potatoes and chickpeas (at the same time works) for about 30 minutes total. Check on the chickpeas every 10 or so minutes for doneness (the chickpeas will likely be done earlier, ~20-25 minutes)
While they are baking, mix carrot ribbons and chopped parsley in a small bowl. Cover with vinegar, salt & pepper and stir to coat. Top with sesame seeds and set aside
To make yogurt sauce, mix all ingredients together and add more lemon and salt to taste. To make a thinner, add more water
To assemble bowls, put some yogurt sauce in the bottom of the bowl, add white rice and top with sweet potatoes, chickpeas, and carrot slaw. Drizzle with some olive oil and more sesame seeds.
