Preheat the oven to 425°
Line a baking sheet with parchment paper or baking mat Wash and peel the outside layer of the butternut squash. Chop into 1 inch thick cubes. Arrange squash onto the baking sheet, spreading out as much as possible.
Pour the frozen broccoli onto the baking sheet. Again, spread out as much as possible. The broccoli and squash can mix, no need to separate.
Add the sliced onion to the baking sheet.
Drizzle olive oil over top, then add garlic, salt and pepper.
Bake for 20 minutes, stir and flip, then continue baking for another 15 minutes. Remove from the oven. (If you are making rice or quinoa, do so now).
Slice the sausages into thin slices, then add to the baking sheet. You can spread this out as well. Stir everything around then place back in the oven for 5 more minutes.
Remove from the oven and serve warm! This is great with rice or quinoa!
