Prepare the Cheese Mixture: Begin by placing the softened cream cheese into a medium-sized mixing bowl. Add the drained crushed pineapple, finely chopped green pepper, finely chopped onion, and seasoned salt. Using an electric mixer, blend these ingredients until the mixture is thoroughly combined and smooth. Cover the bowl with plastic wrap and place it in the refrigerator for 30 minutes to allow the flavors to meld and the mixture to firm up slightly.
Form the Cheese Ball: Remove the cheese mixture from the refrigerator. Using a spatula, scrape the mixture onto a piece of plastic wrap. Use the wrap to help form the mixture into a cohesive ball. This process may be slightly messy as the mixture will be soft; however, the plastic wrap will aid in handling and help maintain a round shape.
Coat the Cheese Ball: Pour the chopped walnuts onto a flat surface such as a plate or a shallow dish. Unwrap the cheese ball and gently roll it in the walnuts, pressing lightly to coat the entire surface evenly with nuts. This step not only adds a textural contrast but also enhances the ball’s appearance.
Chill and Serve: Once coated, rewrap the cheese ball in fresh plastic wrap and refrigerate it overnight to solidify. This chilling period is crucial as it allows the cheese ball to become firm enough to hold its shape when sliced. Before serving, remove the cheese ball from the refrigerator and transfer it to a serving platter. Serve it accompanied by an assortment of crackers and fresh vegetables.
