Boil the pasta. Meanwhile, heat the oil,
add the shallots and gently fry until they
are softened and lightly coloured. Remove
from the frying pan with a slotted spoon.
Increase the heat under the frying pan,
season the steaks and fry on each side
for 3-4 mins, depending on their
thickness and how you like them cooked.
Remove from the heat, transfer to a
board and leave to rest for a few mins.
Drain the pasta, return it to the pan
with the shallots and Stilton, then heat
gently until the cheese starts to melt.
Take the pan off the heat. Slice the steak
and add to the pan with the watercress.
Toss everything together and serve.
