It’s rare that I make up my own recipe. I borrow from others and add or delete ingredients. Frequently, I use AllRecipes.com — this is one of those times. Here is the original recipe: http://allrecipes.com/recipe/chinese-buffet-green-beans/detail.aspx
I made the recipe exactly as written, except that I subbed vegetarian “oyster” sauce for the stuff with shellfish. Yes, you can buy “oyster” sauce with no oysters — and it’s good. I got mine at the Asian market, but it can also be found here: http://www.wanjashan.com/include/N3O2.htm. I also added toasted sesame seeds for a little visual interest.
