Why are you not eating dressing on your salad? There are lots of low-carb options and you can make your own at home. As for adding fat, you don't have to go out of your way to add it, just don't avoid it. I like to put spicy mayo on my hard boiled eggs, though, just add southwest seasonings and fresh garlic to a 1/2 cup of mayo. It keeps in the fridge for days. I also put it on my bunless burgers. Try bacon-wrapped scallops, they're delicious. Again, you don't have to force the fat, just don't go out of your way to avoid it.
