Notes

NOTE:  This recipe serves 8-10 people as a side dish.  You can easily double the recipe and still use a 9x13 inch baking dish.  If you are doing triple the recipe, you will need to use two pans.
NOTE:  To make this ahead of time, cook as directed then cool the casserole to room temp.  Then you can cover tightly with plastic wrap and foil and chill in the refrigerator for up to 24 hours or freeze for up to 2 weeks.
NOTE:  You can use canned and drained, or frozen green beans for this recipe.
