I usually don't count veggies. Corn, carrots and peas get an exception since they have a little more calories to them. If it is a mega-serving - a fill-your-plate type of situation (stir-fry, big salad), then I will since it's more cals. But for 1/2c or a cup it's typically not worth the effort.
Any toppings - butter, sauce, cheese, etc must be tracked. Probably obvious, but I don't want to be confusing.
Also - if you find yourself stalling, maybe track more tightly. But if it works, roll with it.
