Mr.Food has a good recipe book for diabetics. he wrote it with Miss America who also is a diabetic. I have made several of his recipes and liked them all.
Another hint-when making spaghetti I use 1/2 spaghetti and 1/2 zuchinni cut in long narrow strips. Green beads are also good with pasta sauce.
a diabetic must count carbs. I went to the Atkins web site and was able to order,for free, a book called "Atkins Comprehensive CARB counter and Acceptable foods. Its pocket size so you can carry it in your purse.
Another tool I use is www.myfitnesspal.com You put all your info. in and it keeps track of how many carbs,calories etc. you eat daily. its good when you are not sure if you are eating to many or to little carbs. It sure helps me.
There are many low carb recipe sites out there. Here is one of my favorites

Good luck, hope this helps.
