Crock Pot Method: Place all ingredients in a crockpot and heat until cheese has melted. Stir ingredients occasionally to ensure that all are combined. It should take somewhere around an hour to have the cheeses melt (but check because crockpots vary). This particular method is great if you can leave it on the low setting because your dip will stay warm for awhile.
Oven Method: Place all ingredients into an oven safe dish and bake at 350 degrees until the dip is heated through. Stir mixture frequently to combine ingredients.
Microwave Method: Cut the velveeta and cream cheese into cubes and place all ingredients in a microwaveable-safe dish. Heat until cheese has melted and stir to combine all ingredients.
