Place all ingredients in bowl and mix until well combined. Serve cold or transfer to small casserole dish and bake at 400°F until heated through and cheese is melted, about 15 minutes. Or you can add mixture to slow cooker and cook on low 2 to 3 hours, stirring occasionally.
This dip, hot or cold, is great served with crisp celery sticks and crunchy tortilla chips.
