I have been wanting to make this for so long. You can customize this recipe to your liking. I have made the frosting with cream cheese, mayonnaise, and sour cream with salt to taste. The decorations for the cake is also up to you. You can use any sort of salads, lettuce, vegetable even sandwich meat.
This is a savory cake that is similar to a sandwich, but with large amounts of filling and garnish, similar to a layered cream cake. It should be served cold and cut like a dessert cake. I find that it is best to make it a day ahead and just keep it in the fridge. For my filling, I used a mixture of chicken salad. You can alternate several fillings if you want. I have just used one for the entire cake. It is visually very impressive and just as good to eat.
