Adapt it for your goals.
Vegetarian
Replace the Italian sausages with smoked tofu or vegetarian sausages, and add a drained can of chickpeas for extra protein. Roast the chickpeas alongside the veggies from the start.
spicySpicy
Use hot Italian sausage and add an extra pinch of red chili flakes. Toss the vegetables with a teaspoon of cayenne for a fiery kick.
low carbLow-carb
Omit the red onion and add extra broccoli or zucchini. The dish is already naturally low in carbs, but swapping the onion for more cruciferous veggies keeps carbs minimal.

Add one thinly sliced fennel bulb and one apple cut into wedges to the vegetable mix. The fennel's licorice note and apple's sweetness complement the sausage beautifully.
