Preheat oven to 425°F (220°C).
On a large sheet pan, combine: gnocchi (uncooked), smokie pieces, onion wedges.
Toss with: 1½ tbsp olive oil, garlic powder, Italian seasoning, smoked paprika, salt and pepper.
Roast for 20 minutes, stirring once halfway through.
Add the asparagus and broccolini, drizzle with the remaining ½ tbsp olive oil, toss everything together, and return to the oven for 10–12 minutes, until the vegetables are tender and the gnocchi is golden and slightly crisp.
Finish with: Grated Parmesan, a squeeze of fresh lemon, chili flakes (optional).
Before roasting, toss the smokies and onions with: 1 tbsp grainy mustard, 1 tbsp maple syrup, ½ tsp smoked paprika (optional).
