Hotdogs, OK so not exactly gourmet.
Do you have a kettle? You can just add pasta to boiling water, put a lid or a plate and leave for 10 mins. Drain and add some butter, a bit of lemon juice and if you have any basil leaves.
Similar for cous cous (OK I know it is just another pasta but it tastes different). Add chopped spring onion, tomato, maybe some olives.
Can you get anything delivered?
If you have ramakins or tea cups you can 'poach' eggs in the microwave. Rub some butter around the inside of the ramakin, you can microwave to heat the butter but you don't have to.
Put an egg in each ramakin, this bit is IMPORTANT, piece the yolk with a knife. Cook on a low heat for 30secconds and then see if they need longer. If you don't piece the yolk the egg can explode.
I've just seen someone else has recommended eggs this way.
You can also add things to the eggs, cream, grated cheese, ham. You could use lardons but I would cook them in the ramekin for a min first.
If you buy ready prepared veg you can add a bit of water - 2 to 3 teaspoons and cook in the bag.
