This recipe is adapted from simplybakings.com.  It makes 2 generous servings and takes about 15 minutes to make.  How spicy it is depends on which kind of black bean sauce is used.  I used Guilin Style Chili Sauce, and it was moderately spicy.  Also, hoisin sauce can be partially or fully substituted for the black bean sauce if a milder dish is desired.

For the sauce

1.5 Tbs. spicy black bean garlic sauce

2 tsp. soy sauce

2 tsp. black rice vinegar

1.5 tsp. brown sugar

For the green beans

1 Tbs. vegetable oil

1.5 cloves garlic, chopped

8 oz. green beans, trimmed and cut into 2-inch pieces

3/8 cup shitake mushrooms, sliced

3 Tbs. bell peppers, sliced (I used orange peppers)

¼ tsp. sesame oil

2 Tbs. dry roasted peanuts, chopped.

Mix the sauce ingredients together in a small bowl

Heat the vegetable oil in a skillet over medium-high heat.  Add the garlic and sauté for a minute.  Add the green beans and shitakes, and saute, stirring frequently, for about 5 minutes.  Add the bell peppers and cook for another 2 minutes.  Check for doneness.  Add the sauce, and cook stirring frequently, for about a minute.  Check doneness and seasoning.  Drizzle on the sesame oil and chopped peanuts and serve.
