If your meter is accurate, 91 mg/dl glucose is a perfectly normal bloodsugar level. Optimum levels are 70-90 mg/dl. Why in the world would you want a target glucose level of 140-160 mg/dl? That may be an ok upper limit after a meal, but not what I would consider a desirable range. A bloodsugar level of 111 mg/dl is even a bit on the high side in my opinion. High bloodsugar levels are quite damaging to your arteries and nerves.

The reason for your lower than expected bloodsugar 2 hours after your meal is that you are likely experiencing mild reactive hypoglycemia, although the amount of carbs in your meal does not appear to be that high (the only thing that would have significantly raised your bloodsugar would have been the potatoes). If you had measured your bloodsugar at 1 hour post meal, it might have been somewhat higher. Being an early Type II diabetic, you are likely still producing large amounts of insulin. Your pancreas can sometimes overcompensate with the insulin and cause a low bloodsugar level several hours after a meal containing lots of carbohydrate.

Being new to diabetes, your best bet is to experiment with different foods and see how they affect your bloodsugar levels. Refined and easily digested carbohydrates are going to have the biggest impact on your bloodsugar level and are best limited or avoided if you want to keep your bloodsugar levels in the normal range. And I would also try to keep bloodsugar levels below 140 mg/dl at all times, optimally less than 120 mg/dl, and less than 100 mg/dl while fasting.
