1)Soaking cauliflower for 30 minutes will help remove its bitter taste. Also, make sure to remove it from it's heart source when cooking or steaming. Don't let it linger in hot water or accidentally forget about it. The longer cauliflower cooks the more bitter the taste. 2) Be sure to thoroughly rinse quinoa to remove any impurities and bitter taste as well.3) Carefully combine all ingredients to avoid getting a big mush of quinoa and sweet potato. I suggest using two metal spoons to lift and toss the ingredients. Don't stir them!
