In a large skillet over medium heat add 2 tablespoons olive oil, onion, and bell pepper. Sauté for 2-3 minutes or until onions begin to become slightly translucent.
Add additional olive oil and sweet potatoes. Sauté for 6-8 minutes.
Add Brussel sprouts and cook for 3-4 minutes covered, or until Brussel sprouts are almost tender.
While vegetables are cooking whisk together garlic, syrup, vinegar, sriracha sauce, salt, and ground sage in a medium-sized bowl.
Add sauce to skillet, making sure to scrape the bottom of the pan to loosen up any bits. Cook for 2-3 minutes or until potatoes and sprouts are completely cooked.
Serve as a side dish with a sprinkle or parsley or in a cassava flour tortilla for a vegan and Paleo taco and enjoy!
