Preheat oven to 400°F. Prepare your veggies and slice your tofu into thick rectangles.
Place the asparagus and mushrooms in one baking tray, and place the cubed sweet potato in another. Pour enough oil on top of both trays to cover the veggies, and add garlic powder, salt, and pepper to taste. Sprinkle chilli flakes on top of the asparagus for some heat.
Since sweet potato takes longer to cook, put them in the oven first and bake for a total of 30 minutes. After the first 10 minutes, place the asparagus and mushrooms in the oven and bake for a total of 20 minutes.
While the veggies are roasting, boil the quinoa with 2 cups of water or broth. Once the quinoa comes to a boil, reduce heat to low, cover, and let simmer for 15 minutes or until quinoa is soft and fluffy.
To make the spicy peanut sauce, add all the ingredients to a blender or Nutribullet and blend until smooth. Adjust the water and cashews depending on your desired thickness.
Heat a small amount of oil on a skillet on medium-high heat. Saute the tofu slices for a few minutes on both sides until they start to crisp. Set aside.
Once the veggies are done roasting, remove the trays from the oven. Plate up the quinoa, tofu, and veggies, then drizzle on the spicy peanut sauce on top. Top off the bowl with some pumpkin seeds for more texture and protein.
