This I invented during my student days in Exeter...

Tuna Spagetti with Cherry tomatoes in White wine

Salt
Pepper
Olive oil
Butter
Flat leaf parsley chopped
1/2 can of tuna in brine
8-12 cherry tomatoes halved
2-3 cloves of garlic sliced
1 Glass of white wine
Spagetti

Fill a saucepan with water and bring to boil
Add spagetti (boil for 7 to 12 minutes depending on instructions)

Sauce
In a separate pan heat up olive oil and butter.
Add garlic and fry til light golden and fragrant.
Add tuna (drained) and cook for 3 mins
Add cherry tomatoes halves with halved sides facing down, cook for 3 mins pressing down on them so that the juices will escape
Add a splash of white wine (drink the rest)
Sauce is ready (this should take some 7 minutes)
Turn heat off or to low...

Spagetti should be ready now. drain spagetti, toss into sauce, add chopped parsley, and salt and pepper to taste
