Yoghurt - preferably greek or full fat version, unsweetened. With berries, chopped, roasted almonds or psyllium husk if you want. Should land on under 5g carb/100g yoghurt.
If the reason for no-eggs is a time constraint, you could make microwave scrambled eggs. Takes less time than your average tooth brushing session.
Almonds, nuts, seeds.
Cold leftovers if you have any - I love cold stir-fry in the morning - probably me being weird.
Boiled eggs would keep in fridge for several days.
There's a recipe around somewhere on the low-carb forum for a porridge with mainly almond flour and stuff - I wouldn't be surprised if that can be premade and microwave heated too.
