Preheat your oven to 400°F/200°C. Then, line two baking sheets with parchment paper and set aside. No parchment? No prob! Any nonstick baking sheets will do. Next, place the butternut squash, Brussels sprouts and red onion in a mixing bowl, add the 2 Tb. of oil and gently toss it all together until the vegetables are evenly coated.
Then, in a small pinch bowl, stir together the garlic powder, salt and pepper. Toss this mixture in with the vegetables and gently stir again.
Divide the vegetables amongst the two lined baking sheets, spreading them out into evenly spaced single layers. (Tip – don’t wash that mixing bowl just yet! You’ll be using it again.)
Roast vegetables for roughly 30 minutes, adding the chopped pecans to one of the sheets to toast for the last 5 minutes or so. The vegetables are done when the butternut is soft and fork tender and the Brussels are crispy, tender and browned.
While the veggies are roasting, make the Chipotle Pomegranate Sauce by combining all ingredients in a small mixing bowl. Set aside until ready to use.
Also while waiting, in a small bowl, combine pomegranate molasses and water and then set it aside.
Once the vegetables are done roasting, return them to that previously used mixing bowl, add the molasses/water mixture and the pomegranate seeds and stir to combine. Set this aside.
Lastly, prepare your corn tortillas. I do this by placing them directly on the fire on the stove. They only need about 10 seconds on each side. FYI - always use metal tongs to handle the tortillas during this process - never use your fingers! The tortillas can also be warmed in a skillet with or without a bit of oil added. Anyway you approach it, the goal is to cook them on each side just until they start to puff up or brown.
Assemble tacos by filling each tortilla with the roasted vegetable mixture and then top with Chipotle Pomegranate Sauce. If you want to make them extra pretty, top with a few extra pomegranate seeds, too.
