Do what you can to learn to love spinach. It's one of the best foods for you . Avoid iceberg lettuce, it's mostly just water, not too many nutrients in there.
Also be careful with the meats, dressings etc if you're watching calories, they add up faster than you think. A Cesar salad will usually have as many calories as a Big Mac for instance (healthier for you, but still pretty bad).
If you really just don't like salads, just eat more vegetables.
You can blend up green leafy vegetables and fruit in a blender, it makes a pretty good smoothie. It's a tasty way to get fruits and vegetables.
Here's a bunch of info on Green Smoothies:

You'll be amazed how much better you feel in just a couple of weeks if you can pick up the exercise a little and increase your vegetable intake.
Good luck!
