To improve salads I add more things to them such as different dressings, any meat, esp. bacon, hard boiled eggs, different cheese, sunflower seeds, stuff like that.

I'm not quite sure what the carb count is for zucchini but if it's pretty equal and that's what it takes for you to eat your veggies, then go for it. I would recommend that you do try alternating w/other veggies so you don't get burnt out.
