Green Bean Casserole

This is one of our favorite ways to eat Green Beans - I found it in "More of the Four Ingredient Cookbook."  (Love 4 ingredients!!)

2 (16 ounce) cans of whole green beans, drained (I like to use the French sliced)
1/2 cup French dressing (sometimes I use some of the other variations, especially if they are lower calorie)
1/2 cup chopped onion (if I am just pulling stuff out of the pantry I will use dried onion and use less)
6 to 9 strips of bacon, cooked and crumbled (another short cut is to use real bacon bits but fresh bacon tastes better)

Combine first 3 ingredients.  Place in casserole.  Sprinkle with bacon and bake for 30 minutes at 350 degrees.

If it is just the four of us, I may use only one can and do half.
