Not sure why Jimmy recommends less carbs, I was going to say more carbs. I thought cutting carbs was supposed to make you lose weight? I don't know if you're low-carb or not, but it seems like the majority of folks new to paleo go low-carb (probably because of Sisson, Wolf, Cordain, etc.). If you are low-carb, reintroducing foods like potatoes might do the trick.
Other suggestions:
I find bone broth extremely satisfying and satiating in a way that few other foods are to me. You can also use it for sauces on meats and put it in lots of other stuff, liked mashed potatoes. You may want to try this, along with some offal, if you can stomach it.I like to make an Asian-style savory steamed egg custard with pork bone broth.
Obviously, slather everything with butter.
Obviously again, don't worry about over-eating. You may want to try upping the quantity of food consumed at each meal rather than grazing. Eat until you are full. Salad sounds very low-calorie to me, even a Mark Sisson style big-ass salad. At least add some meat or seafood to it!
Prefer red meats- I find these more satiating for a longer time, and they're better for you than chicken, or even pork. Maybe steak and eggs for breakfast.
I have no idea if this is true for you, but the thought occurred to me that you might have some hang-ups about food. If this is true, you should deal with that. Being a picky eater is the way to a lot of problems, in my experience.
