This asparagus casserole goes great with just about any meal. I've prepared it ahead of time, then popped it in the oven so it's ready with the meal. —Judy Fleetwood, Beulah, Michigan

Soft Bread Crumbs

To make soft bread crumbs, tear bread into pieces and place in a food processor or blender. Cover and pulse until crumbs form. One slice of bread yields 1/2 to 3/4 cup crumbs.
