For dressing, place evaporated milk, cranberry sauce and Italian dressing in small jar or container; cover tightly with lid. Shake for 1-2 minutes. Makes about 1-1/2 cups.
Dressing can be made in advance and refrigerated for up to 2 days. Shake well before using.
For salad, toss greens, turkey, blue cheese and 3/4 cup dressing in large bowl. Sprinkle with cranberries and walnuts.
Serve immediately and with additional dressing, if desired. Refrigerate any remaining dressing.
