I disapprove of advertising here, but I commend the OP for asking first.

My DH has had very good luck with Better Oats brand organic Raw pure &
simple multigrain hot cereal with flax. Its mostly oatmeal but in
controlled portions and is less than two carb counts 28 g. with 3 g.
dietary fiber) a serving. It does not spike him.

The cereal contains oats, barley, wheat, flaxseed, quinoa and rye. All
organic grains.

He likes his hot cereal with salt and pepper, no sweetener or butter or
milk.
