In a bowl take ice water and drop blanched beans in it.
This will stop the overcooking of beans and retain its green color.
After 2 - 3 minutes remove beans from ice water and wipe it with a clean towel.
Now in a skillet or pan, heat butter or oil.
Add finely chopped garlic and on a low flame saute for 15 - 20 seconds or till it starts to change color.
Now add blanched beans into the skillet
Add a little salt (to taste) and black pepper.
On a medium flame keep sauteing for 3 - 4 minutes.
Don't overcook the beans as the texture we need should be tender and crisp. Not soggy ones.
Remove from heat and serve hot.
Notes
Don't over cook beans and keep the texture tender and crisp.Wash with ice water immediately after you blanch the beans.Use garlic generously for flavor.
