Wrap 7 green beans with bacon and place in prepared dish. Repeat, using all the beans and bacon. The bundles can be packed tightly in the dish if needed.

Combine melted butter with brown sugar and garlic salt. Pour over the green bean bundles
Cover with foil and bake for 35 minutes. Uncover, turn up to 400° and bake another 20 minutes. This will get the bacon cooked better.
