Always on the lookout for monotony-breaking food items, I stumbled upon this tandoori chicken w/ spinach microwavable.

You can get them at your local grocery store (not Walmart, I don't think), Vitamin cottage, etc.

They have 6g total carbs, and 3 of those are dietary fiber.

Vitamin Cottage on Nevada here in COS had them on a markdown sale price. I cleaned them out.
