Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Peel and cube the sweet potato into half-inch pieces, then drain and rinse the chickpeas, patting them very dry with a towel to ensure they get crispy.
Place the sweet potatoes and chickpeas on the baking sheet, drizzle with olive oil, and sprinkle with cumin, smoked paprika, sea salt, and black pepper.
Toss the vegetables until evenly coated and spread them out in a single layer, ensuring they aren't crowded so they roast rather than steam.
Roast in the oven for 25 to 30 minutes, tossing halfway through, until the sweet potatoes are fork-tender and the chickpeas are golden and slightly crunchy.
While the vegetables roast, place the fresh baby spinach into a large serving bowl.
Once the roasted ingredients are ready, layer them over the bed of spinach to slightly wilt the leaves with their heat.
Top the bowl with the cottage cheese and finish with a bright squeeze of fresh lemon juice before serving.
