I made this for a party once and it was the first appetizer gone! Serve with toasted sliced baguettes, tortilla chips, or crackers.
Stir together cream cheese and mayonnaise in a large bowl until smooth. Stir in green chiles and jalapeno peppers. Pour mixture into an oven-proof dish. Combine parmesan cheese and panko and sprinkle on top.
Bake at 375 degrees for 30 minutes.
