Porridge fingers are great. You can add dried fruit and all sorts to them to make them more interesting. Same quantity in tablespoons of oats (Quaker is great!) and milk, mix together, allow to soak for a short time (although that's not really necessary), flatten the top then 2 minutes in an 800w microwave (adjust time to suit alternative wattage). Either cut into fingers or quarters. I'd start with 2tbsp and work from there.
