Cook the green beans in boiling, salted
water for 3-4 mins, until just tender.
Drain and cool under cold running water.
This can be done the day before – just
keep the beans covered in the fridge.
When you’re ready to eat, heat the
butter in a large frying pan until foaming,
add the shallots and cook for 4-5 mins,
until soft but not coloured. Throw in
the beans and toss to coat. Cook for
1-2 mins until heated through, then
season. Serve with the pork.
