In a large mixing bowl, combine the cream cheese, shredded cheese, chopped bell pepper, chopped onion, lemon juice, orange juice, garlic powder, pepper, onion powder, and dill together. *you can use your hands or an electric mixer to combine. If you use an electric mixer, keep the speed on low.
Use a spoon to give your cheese spread a taste test. It may need more citrus, garlic, or other seasonings to get it to your liking.
Form the cheese mixture into a christmas tree (or any shape!)
Coat the tree with chopped walnuts. You can add tomatoes and bell peppers to make it even more festive.
Surround the tree with crackers and vegetables for dipping. This cheese spread is also good with carrots.
