Arrange two oven racks to divide the space into thirds. Preheat your oven to 425°F. Spread the diced root vegetables across a large rimmed baking sheet. Drizzle with 2 tablespoons of olive oil, season with 1/2 teaspoon kosher salt and black pepper. Toss to coat, spread evenly, and roast on the lower rack for 20 minutes.
Remove the root vegetables from the oven, flip them, and push them to one side of the pan. Pour pumpkin seeds onto the empty side and crumble the feta cheese directly over the hot root vegetables.
Spread the cauliflower rice evenly across a second rimmed baking sheet. Sprinkle with turmeric, drizzle with 1 tablespoon olive oil, and season with 1/2 teaspoon kosher salt and black pepper. Toss thoroughly and spread into an even layer.
Place the root vegetable pan on the upper rack and the cauliflower rice pan on the lower rack. Roast together for another 7 to 10 minutes until seeds are toasted and cheese is soft.
In a mixing bowl, toss the drained chickpeas, chopped cilantro, lime zest, lime juice, 1 tablespoon olive oil, 1/2 teaspoon kosher salt, and black pepper. Stir until fully coated.
Divide the warm cauliflower rice among 4 bowls. Top with the roasted vegetable and feta mixture, followed by the zesty chickpea salad. Sprinkle with toasted pumpkin seeds and add a quarter of the avocado to each bowl. Serve with extra lime wedges.
