Pre-heat oven to 425 degrees. Drain green beans. Cut bacon slices in half. Wrap a good hand full (12-15) beans with the bacon & lay seam side down on a lined sheet pan sprayed with pam. Repeat with remaining beans and bacon. Bake about 25-30 minute until bacon is brown & beans are cooked. Meanwhile, grate 1/4 to 1/2 of an onion to get it's juice and mix with the rest of the ingredients in a glass pyrex. Microwave 1-2 minutes until butter is melted. Stir well. When bundles are done dip each bundle in sauce and place in serving dish. Pour remaining sauce over bundles and serve. These bundles can be assembled in advance with the sauce kept seperate. These bundles do not freeze well raw or pre-cooked.
