Begin by gathering all your ingredients. Ensure the cream cheese is properly softened to make mixing easier.
In a large mixing bowl, add the softened cream cheese and mayo. Using a spatula or wooden spoon, mix until smooth and creamy.
Add the chopped salami, shredded cheddar cheese, chopped green onions, salt, and black pepper to the cream cheese mixture. Stir well until all ingredients are evenly combined.
Lay a piece of plastic wrap on your countertop. Scoop the mixture onto the center of the wrap and shape it into a ball. Once formed, twist the ends of the wrap to secure the shape.
Place the wrapped cheese ball in the refrigerator for at least 2 hours, or until it’s firm enough to hold its shape.
Once chilled, unwrap the cheese ball and place it on a serving platter. Pair it with your favorite dippers, such as crackers, pretzels, or fresh vegetables.
