Heat oven to 350°F. In large bowl with electric mixer, beat cream cheese, sour cream and salsa on medium speed until well blended. Add all remaining ingredients except cilantro and bread; beat on low speed until thoroughly mixed. Spoon mixture into ungreased 9- or 10-inch pie pan or quiche dish.
Bake 20 to 30 minutes or until thoroughly heated. Sprinkle with cilantro. Serve warm with bread slices for dipping. Store in refrigerator.
