There is a hamburger place here (Snuffers) that has the BEST cheesse french fries you have ever eaten (bummer now), but they also make very good HUGE hamburgers. I went there for lunch a couple of times lately and ordered the Bacon Bleu Cheese burger with no bun with wonderful results. When the meal started my BG was 104, 1 hr PP it was 97, 2hr PP it was up to 101.
The main lesson for me is to try new stuff and watch my meter. I can also eat 1/2 baked potato with a very small spike.
