You could do microwave/quick oats? I know unprocessed are the best but I don't have time to do the stovetop bit in the morning so I microwave porridge then add lots of goodies such as.

Coconut cream
Banana
Pear and cinnamon
Currants or sultanas
Almonds
Almond milk
Diced peaches

All with a slurp of honey

I also make my own muesli-

Rolled oats
Raisins
Currants
Sultanas
Pumpkin seeds
Sunflower kernels
Coconut chips
Flax
Chia seeds
Slithered almonds

You can lightly toast in oven with coconut oil or use as is.
