Preheat oven to 425℉ and put an empty baking sheet in the preheating oven.
Toss together the squash, sweet potatoes, brussel sprouts, olive oil, rosemary, 1 tsp thyme, salt and pepper.
When the oven is preheated, pull the hot pan out of the oven and immediately spread the vegetable mix on the pan.
Place the pan back in the oven, and bake for 30 minutes, stirring the vegetables around half way through the cook time.
When the vegetables are cooked, remove them from the oven and add them to a bowl.
Add the cranberries, pecans, cheese, and bacon, if using, to the bowl of vegetables.
In a separate dish, whisk together the syrup, vinegar, mustard, garlic, 1 tsp thyme, and salt.
Add the dressing to the vegetables, and toss to combine.
Enjoy!
