One of the things that I loved the most on our RCCL cruise were the fruit soups. I assume they have them on all ships. I would have them every night as an appetizer and then have a salad. After a very hot day in the Caribbean, the cold soups were wonderful!
After the salad, you have the main course. Every night, there are 4-5 different items - They are usually foods for that evening's particular theme. There are also 3-4 items that they have every night, like steak and such. If you try something you don't like, you can always request something different.
You also have a choice of 4-5 desserts every evening. Many people try 2-3 of them.
Enjoy your cruise!!
