01 - Preheat oven to 400°F. Line a baking tray with parchment paper.
02 - Toss sweet potato cubes with 1 tbsp olive oil, salt, and pepper. Spread on the tray and roast for 25 minutes, turning halfway, until tender and golden. Set aside to cool slightly.
03 - While the sweet potatoes roast, combine ground lamb, onion, garlic, parsley, cumin, coriander, paprika, egg, breadcrumbs, salt, and pepper in a large bowl. Mix until just combined.
04 - Shape the mixture into 8–10 rissoles (small patties), about 3/4 inch thick.
05 - Heat 2 tbsp olive oil in a large skillet over medium heat. Cook rissoles for 4–5 minutes per side, or until browned and cooked through. Transfer to a plate and keep warm.
06 - In a small bowl, whisk together the dressing ingredients until emulsified.
07 - In a large salad bowl, combine roasted sweet potatoes, baby spinach, red onion, feta, and pumpkin seeds. Drizzle with the dressing and gently toss to coat.
08 - Serve lamb rissoles warm alongside the sweet potato salad.
