Green and yellow beans with sesame seed sauce

This recipe is great! I love the sauce used on the green beans and use it with all sorts of vegetables, from cucumber and carrots to snow peas and sugar snap peas from the garden. It also goes well with tofu, and makes a good dip for summer rolls. I thin it out a bit for dipping and usually serve in small bowls. It's also adaptable and takes well to additions or substitutions. Very simple to make. (I use tahini instead of grinding my own sesame seeds)
