Because they are Thai crisps, we took inspiration from the classic Thai "crying tiger" steak - fish sauce, lots of herbs, spice. The result? Deeply delicious.
Mix the steak marinade ingredients together and add the steaks, moving them around to coat them. Pop in the fridge for around 2 hours.
In the meantime, whisk all the dressing ingredients together. Check the seasoning.
Heat a skillet (or do it on the BBQ) and grill your steaks until they are the internal temp you like - 45°C with a temp probe will give you a rare steak.
Slice the steak and toss it with the crisps, sauce, herbs, mangetout and any other things you might like.
