Not necessarily, some people can eat it just fine. There were some suggestions in the other thread you posted but some I've had that were close to 15 were: One-half vegie sausage, scrambled with vegies and 1/3 Cup milk for my capp and eggs = 16, An omelette with vegies and the milk =12. Or the toast and peanut butter or toast with cheese or egg (1 slice toast) all would work. You also could have a tortilla that is small or a low carb wrap with eggs, vegies, cheese, meat, whatever
I wouldn't stress on this too much, denise, remember what you're doing now is gathering data. Later on when you get your I:C ratios right you can make different choices about food.
