I have found salad to be something of a slider for me, too - which isn't really a bad thing considering the high nutritional density of most salads (if you do them right and don't load them up with a lot of high calorie junk!) I found when starting with salads a month or so out that if I cut back my normal serving capacity of meat from 3 oz to 2, that I had comfortable room for another 3ish oz of salad veg (typically chopped spinach, avo, tomato, green onion and bell pepper, and/or whatever else I had around. I found it a convenient way to get in at least a token amount of veg, and make my eating a bit more "normal" than typical post-op fare, which made for less of a "being on a diet" feeling and reinforced what good sustainable eating habits that I already had. Such salads are still a staple of my diet five years later.
