I soak 2 dsps wholegrain oats (groats) in hot water overnight (thermos) and reheat with butter and coconut oil in the morning. I also add berries, sweetener, chia, flax, cinnamon depending on what's in the cupboard. There is also a recipe on here somewhere for porridge with an egg beaten in. Anything a bit carby I eat in moderation with fat added to try to spread and lessen the rise in BS. I don't call it a spike, which is what I would get with fruit juice, for example.
