DR elmore - You probably should have just had the soup for lunch, and saved the salad for your next small meal about three hours from now. The mushroom-barley soup is quite hearty, so... but at least it was barley and not egg noodles. Eat slower, slowly, and be aware that you're chewing your food. Your blood sugar will spike after eating any meal, so you need to make sure to keep those spikes as small as possible throughout the day. Smaller meals equal smaller spikes.
