I took a Nutrition class through Coursera which focused intently at diets for diabetics. Carbs aren't the enemy and shouldn't spike or drop your blood sugar if you eat them in a balanced way throughout the day. The carbs that you do have should be loaded with fiber since that slows down glycemic response. It sounds like you are doing that with fruits and vegetables. But I think you should try adding whole grains and legumes back into your meals to save some money and fill you up longer.
I have two siblings who are hypoglycemic so I've seen their struggles with diet my entire life. It does require more thought and planning than the average person wants to put into eating.
It might be helpful for you to read the info at :
http://www.mayoclinic.com/health/diabetes-diet/DA00027 The nutritionist in my class said the recommended balance of nutrients be 55% carb, 25% fat and 20% protein(I don't have blood sugar problems but I am now using this balance with excellent results!)
A breakfast of just pancakes, even whole wheat, will wreck havoc with your blood sugar, as would a breakfast of just bacon or just eggs or just fruit. Every meal and snack should be as balanced as possible. A couple whole wheat pancakes with peanut butter, a couple strips of turkey bacon and piece of whole fruit and yogurt would be an example of an ideal, well-balance meal for stable blood sugar levels.
With your special dietary requirements you should definitely be using a tracker(Sparkpeople , Super Tracker, My fitness pal)until your are able to balance your eating as second nature.
BTW, my family of five eats Flexitarian with the above balanced percentages and I spend $2 per person, per day on food, no eating out or alcohol. We are all slim and healthy.
Since you do rely so heavily on fresh produce, look around for a local co-op group that will buy in bulk and reduce your expense in that area. We have Bountiful Baskets in CO but I'm pretty sure they don't have that in VA yet. But most areas have some groups that do this. Look in your local papers and ads and ask around, especially in health food and natural item stores.
