Preheat oven and prep veggies: Preheat oven to 400 degrees F (200 C), then wash and cut vegetables. Slice the ends off of zucchini, then cut into ¼ inch (½ centimeter) slices. Cut the ends off sweet potatoes, then cut into small ½ inch cubes for roasting.
Season vegetables: Place sliced zucchini and sweet potatoes on a baking sheet and mix with a drizzle of olive oil. Once completely coated in oil, season the vegetables with sliced garlic, salt, pepper and any other dried or fresh herbs that you prefer.
Roast vegetables: Bake veggies in the oven until soft and brown around the edges, which will take about 25 minutes. 10-15 minutes into cooking, toss the vegetables so they brown on all sides. Remove from the oven and serve immediately as a side dish, or let them cool and mix into salads.
