Put the water on to boil the pasta, and put the pasta in with some salt once boiling.
Meanwhile, slice the tomatoes in half.
Warm the oil in a large frying pan a sprinkle in the chilli flakes and add the tomato halves.
Cook for about five minutes, turning over occasionally.
Steam or boil the greens until tender.
Add the seafood, parsley and season with salt the pepper. Cook over and medium to low heat for a few minutes. The seafood will let out quite a bit of liquid as it cooks.
Once the pasta is al dente, add it to the pan along with the kale and lemon juice, and continue cooking on low for a few minutes so the pasta absorbs most of the liquid and the flavours mingle.
