- STEP 1
Make the tomato sauce first. Heat the olive oil in a frying pan, and keep on a medium heat: fry the onion and garlic for about 7-8 minutes.
- STEP 2
Add the anchovies and fry for a further 2 minutes. Keep on a medium heat, as you want the onion to saute but not catch. The anchovies, by this stage, should have almost melted away into the oil.
- STEP 3
Turn the heat up, and add the tomatoes. Allow to bubble furiously for a minute, then turn the heat down to a simmer. Add the pepper, sugar, vinegar and basil and simmer slowly on a low heat for about an hour or so, topping up with a splash of water if the sauce becomes too dry.
- STEP 4
After an hour, taste for seasoning, add the lemon zest and juice, and stir well.
- STEP 5
Steam your greens very lightly- for 2-3 minutes on a rapid boil, then remove and mix with the tomato sauce. Place in a suitable bowl, and sprinkle with the chopped herbs, crumbled feta and toasted nuts.
