Rinse your quinoa well under cold water to help remove some of the bitterness.
Spray the inside of your pressure cooker lightly with cooking spray. Then add the quinoa, vegetable stock, and 1 teaspoon of salt. Turn the lid to the locking position and make sure that the top vent is set to "Seal" and not "Vent" in order to build pressure. Turn the pressure cooker function on and set the timer to 1 minute.
After the pressure has built and the 1 minute timer has elapsed, let the quinoa sit inside the pressure cooker for 7 minutes. Then release the pressure manually on top. Fluff with a fork and remove the quinoa and spread it onto a cookie sheet in order to let it cool so it doesn't get mushy.
While the quinoa is cooking, preheat your oven to 400 degrees. On a sheet pan, add your cubed butternut squash, halved brussel sprouts and red onion wedges. Drizzle them with 1-2 tbsp of olive oil and 1/2 tsp of kosher salt. Sprinkle 1/4 tsp each of ground cinnamon and cardamom over the butternut squash. Massage the oil and spices into the veggies. Roast in the oven for about 20 minutes, or until the veggies are fork tender and nicely caramelized.
You can leave the kale raw, or lightly saute it in a frying pan over medium-low heat with 1 tbsp of avocado oil and a pinch of kosher salt until slightly wilted.
Combine kale, quinoa, and roasted veggies into a bowl. Top with pomegranate seeds and serve with maple tahini dressing.
