I know you are supposed to count an entire recipe's nutritional value when calculating points and not just count the zero points items as zero. But what if there is just one non-zero item added.

In particular, I was going to make a lunch salad:

1. Cucumber
2. Tomato
3. Mushrooms
4. On can of non-oil tuna

The small 70 g can of tuna (which only has 49 calories by the way) calculates out to 1 point plus (I see you use ProPoints here - I guess it's basically the same?).

Is it reasonable to therefore say the salad is a 1 point salad?

One followup question: 2 T of non oil dressing (4 cal per T) is zero points, isn't it?
