I'm not that familiar with diabetic can and can't eats, and don't know the carb count, but if anyone can eat whole wheat pastas is the best one I have found. I sauteed garlic, peas, asparagus, peppers in some butter and tossed it with the penne, a little olive oil and parmesan. I am going to make the same with TJ's quinoa blend next week.
It was very simple and very tasty. My wife even liked it.
Hope this helps if it fits within your diet.
