Fried eggs with either potato waffles cooked in the toaster (I set it to maximum and when the lever pings up I do it again) or a microwaved baking potato cut into two or three slices and lightly sauted in the same pan as the eggs. I eat plenty of fruit and veg so don't worry about not having any in a meal once in a way.
Hummus and pita, with crudites if I can be bothered.
Cheese on toast.
Almost anything where eggs are the main feature.
Filled fresh pasta served with grated parmesan or pesto. Salad on the side if I have sufficient energy. I like the idea of cooking peas with the pasta.
Some form of pre-cooked protein (e.g. ham, chicken, prawns, falafel) and salad with decent bread on the side.
Microwaved baking potato with beans, cheese and a little finely chopped spring onion.
Leftovers re-heated. This can be wonderful. Lots of things develop in flavour and taste better on the second day.
