Eggs, sausage, bacon, ham, cheeses, omlettes,. those are the main things. for variety I'll ocasionally have cheese on a low carb peice of bread, or some plain yogurt, or a glass of milk. Watch the carbs on these last ones though, make sure you have the allotment. Also, you could eat any food you might eat for lunch or dinner even if it's 'breakfast' time.
