Prepare Squash & Brussels Sprouts- Wash squash and sprouts. Trim both ends of squash and slice horizontally down the middle. Use a spoon to remove seeds from squash and then slice into about ⅓ inch wide slices. Trim ends off of Brussels Sprouts and remove any outer leaves that do not appear fresh. Leave tiny sprouts whole and half any larger sprouts.
Mix the Marinade- In a large mixing bowl add all marinade ingredients and mix to fully combine
Add prepared squash and sprouts into bowl with marinade and mix until everything is coated very well.
On two baking sheets, lined with a non-stick liner or parchment paper, add veggies in a single layer with no overlap, leaving some space between everything. (Try to minimize extra marinade on the pan, as it will burn with no oil added to the recipe.)
Bake for 15 minutes, flip and bake another 8-10 minutes, until veggies are browned and squash is tender. Enjoy!
