Brown the ground Italian sausage over medium heat. Drain and discard the grease.
Put the whole milk, cubed Velveeta, and cubed cream cheese into a pot. Cook and stir, scraping the bottom of the pot, over low heat until the cheeses are melted.
Stir in the cooked sausage, drained Rotel (reserve 2 tablespoons for garnish), diced jalapenos, minced garlic, and ground cumin. Cook and stir over low heat until heated through.
Transfer to a casserole dish, if desired. Garnish with reserved Rotel and chopped cilantro.

Notes
Keep Warm: Transfer the dip to an oven-safe casserole dish and place it in the oven on low (220˚F) for 20-30 minutes, then stir and garnish before serving. Or you can keep the dip warm in a slow cooker on the lowest setting, stirring it occasionally.Storage: Store the leftovers in an airtight container in the fridge for 3-4 days. Reheat in the microwave in 30-second intervals, stirring after each interval. Or in a large pot on the stovetop over low heat while stirring.
