1) Do not allow millet to cool completely before adding the sauce ingredients. Otherwise you will end up with clumps of tomato paste in your salad. 2) Keep salad tasting fresh for a week by keeping it in an airtight container in the fridge. 3) This might seem obvious but make sure you always buy millet suitable for human consumption. Millet for animal use is most often still has an outer hull that can't be digested by humans. Therefore, make sure when you buy millet is says hulled somewhere on the packaging.
