Rinse, drain quinoa (if buying from bulk bin). Add quinoa and water to small pot. Bring to boil, cover with lid. Cook for 15 minutes. Immediately uncover and spread out on baking sheet. Let cool completely.
To roast, adjust rack to upper 1/3 (but not any higher) and preheat broiler. Roast quinoa for 5 minutes, stir and rotate pan. Roast additional 3 minutes, but check frequently. If you have a super powered broiler, you might want to lower rack or turn broiler to low.
