01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Toss sweet potato cubes with 1 tablespoon olive oil, salt, and pepper. Spread evenly on prepared baking sheet. Roast for 25 minutes, turning halfway through, until tender and golden brown. Set aside to cool slightly.
03 - While sweet potatoes roast, combine ground lamb, onion, garlic, parsley, cumin, coriander, paprika, egg, breadcrumbs, salt, and pepper in a large mixing bowl. Mix until just combined, being careful not to overwork the meat.
04 - Form the mixture into 8 to 10 patties, approximately 3/4-inch thick.
05 - Heat 2 tablespoons olive oil in a large skillet over medium heat. Cook rissoles for 4 to 5 minutes per side until well-browned and cooked through. Transfer to a plate and tent with foil to keep warm.
06 - Whisk together extra virgin olive oil, lemon juice, Dijon mustard, honey, salt, and pepper in a small bowl until emulsified.
07 - Combine roasted sweet potatoes, baby spinach, red onion, feta cheese, and pumpkin seeds in a large salad bowl. Drizzle with dressing and toss gently to coat evenly.
08 - Plate lamb rissoles alongside sweet potato salad and serve immediately while rissoles are still warm.
