Step 1

If using fresh green beans clean them, cut them and blanch them in a pot of boiling water for 2 minutes. If using canned green beans drain them in a colander.

Step 2

Mix the soup and milk together in a bowl. Stir it so it is smooth and all the lumps are gone. Then stir in the soy sauce.

Step 3

Stir in the green beans and 2/3 of a cup of the onions (about half). Add pepper to taste and mix everything well.

Step 4

Step 5

Cook In the Oven: Bake at 350 degrees F for 25 minutes. Stir, then sprinkle the remaining onions on top and bake for 5 more minutes until they are golden brown.
