In a large cast iron skillet or stew pot, brown the meat over medium-high heat. If needed, drain the grease.
Stir in the onion, seasoning, garlic cloves, green chilis, macaroni and broth.
Cover and bring to a simmer for about 12 to 15 minutes, or until the macaroni is tender.
Remove the pan from the heat and stir in the sour cream and cream cheese until smooth.
Place the pan over low heat and stir in the cheeses. Cook until the cheese has melted, stirring occasionally. Serve warm.
