Terrible photo of a dubious looking Bert, but it was actually delicious. I have to take the photos by stealth these days or much fury follows at the sight of a phone he’s not allowed to play with at the table. (Naughty, hypocritical mummy.)

Serves 3

1 tbsp  vegetable oil

Leftover beef cut into thin strips

1 green pepper, cut into thin rings, deseeded

1.5 leeks, sliced

5 or 6 white mushrooms, sliced

For the sauce:

30g  dry roasted cashews

1 shallot, peeled and chopped

1/2 teaspoon chili flakes

1 clove garlic, peeled

1 inch fresh ginger, grated

2 tablespoons soft brown sugar

3 tablespoons Thai fish sauce

3 tablespoons toasted sesame oil

Juice of one lime (or 1 tablespoon lime juice)

Stalks of bunch of fresh corander, roughly chopped

Blend all the ingredients for the sauce until smooth. Fry the veg for 2-3 minutes, then add the sauce and beef and cook for another minute or two. Garnish with more roughly chopped nuts and the chopped leaves of the coriander, if this won’t infuriate your child.

I made the mistake of cooking the veg too long so they failed to pass the very stringent toddler slime test. Next time I’ll make sure they were crunchy. I’m getting enough finger wags and ‘naughty mummy’s at the moment as it is.
