Turn oven on at 350F and prepare a baking sheet with parchment paper.
Place the sweet potato and zucchini on the baking sheet and sprinkle paprika and cumin on top. Mix together with your hands to ensure all veggies are coated with the spices.
Roast for 30-35 minutes, or until the sweet potato is tender.
In a separate frying pan, saute the onion with the garlic until the onion is soft.
Add the sausage pieces and fry until cooked through.
Add the sweet potato and zucchini to the frying pan and toss until heated through.
At the last moment, add the spinach and allow to wilt.
