Ok, so having a big meal of fish and chips is not the kind of reward we’re talking about here.  But when you’re having plenty of veges and salad, it’s ok to sometimes put something like a nice lean steak or a couple of meatballs or rissoles on the side for a delicious addition to your meal.  No, they’re not low fat as such, but as long as you don’t overdo the amount of food you’re putting on the plate in the first place (ie - just one steak or one rissole with a little gravy), you’re set.
