I found Utz Hulless Puff'n Corn at a truck stop in Pennsylvania. They also come in Cheese Flavor (15 carbs in 2 cups), Butter Popcorn (not hulless--13 carbs in 2 cups, and White Cheddar Popcorn (not hulless--15 carbs in 2 cups). They have a website at UTZ Products

Here's the nutrition information for the original Puff'n Corn flavor:
Serving Size: 2 cups (about 30 grams)
Calories: 180
Total Fat: 15 grams
Total Carbohydrates: 11 grams
Total Fiber: 0 grams
Total Protein: 1 gram

A half-cup would be a nice crunch for only 3 carbs.

Hope this is helpful.
