Molten cheese loaded with spicy chorizo.
Heat a skillet over medium heat. Cook and stir the chorizo sausage in there until it's cooked completely, 5 to 7 minutes. Drain out the grease and transfer the sausage to a slow cooker.
In the slow cooker pot, along with the chorizo, stir in the diced tomatoes, cream cheese, and processed cheese.
Cook the pot on Low for 1 1/2 to 2 hours or until cheese is melted, stirring occasionally.
