Heat a non-stick skillet over medium high heat. Add beef and cook until browned. Transfer to a crockpot and return skillet to the stove.
Add carrots, mushrooms, onions and garlic to the pan and saute until starting to soften. Transfer to the crockpot. Add quinoa.
In a small mixing bowl, mix together remaining ingredients, minus water, salt and pepper. Pour this sauce over the ingredients inside the crockpot. Add water and stir together.
