1 (12 oz.) can evaporated milk
2 cans of water (reuse the evaporated milk can for this)
1 lb. processed cheese, cubed (like Velveta)
½ Cup onion, minced or diced (I love the taste of red onions in this recipe!)
In a slow cooker/crockpot, mix all ingredients together. Cover and cook on low heat for 3 – 4 hours stirring occasionally.
Suggested toppings: broccoli, bacon and/or diced ham.
This is the easiest recipe I have every found. It freezes and reheats well too.
