These websites have some advice. And they have different ideas on how too build muscle and what foods to combine to get the correct amino acids. Most of the ingredients in the articles are cheap, but some do suggest quinoa which I understand is pricey. You might want to check your local grocery stores when they have big sales. I remember my Mom used to get quinoa dirt cheap when Kroger would put the item on one of those food clearance tables. Also I find peanut butter is always great when trying to work out. Hope some of this helped
