Heat a skillet to medium high heat and cook the ground beef and the taco seasoning until the beef is no longer pink. Drain off the excess fat if needed.
Cut the cream cheese and the velveeta into about 1 inch squares for quicker melting.
HEATING OPTIONS:
Add the cooked beef and all other ingredients to a slow cooker and cook on high for 2 hours (stirring occasionally). After the 2 hours, keep on "warm" for serving.
OR...(my preferred & quicker method)Add the cheese, salsa, and cream cheese to a large bowl, and heat in the microwave in 1 minute intervals, stirring in between each minute. (Usually takes about 3 minutes to fully melt. You can then add this to a slow cooker as well and keep on warm for serving.
