I literally eat nuts for breakfast. It's rather gross, really... I have 4 tablespoons sunflower seeds, 2 tablespoons almonds, and 2 tablespoons walnuts. All of this amounts to about 8 carbs. I don't spike, and I don't have hypoglycemia before lunch.
I also make a chocolate drink using 1 tablespoon unsweetened cocoa powder (1 carb), an egg, a pinch of salt, ginger powder, cinnamon powder, and a splash of milk. You whip together everything in a cup and then pour boiling water into it while stirring. The egg cooks and you get a low-carb, creamy, chocolaty drink! It's not sweet, but I like it. Another good food to help prevent spiking.
