Preheat the oven to 200ºC/180ºC Fan/400ºF (gas mark 6).
Carefully cut each of the peppers in half through the stalk and then carefully remove the seeds and pith from inside. Arrange the pepper halves, cut side up, in the roasting tray.
Divide the tomato halves between the pepper halves and then do the same with the chopped garlic.
Using a pair of scissors, snip one anchovy fillet into each pepper half.
Add 1 dessertspoon of olive oil to each pepper half.
Season with a little black pepper. The anchovies should ensure that adding salt is not necessary.
Bake in the preheated oven for 30 mins or until soft and golden.
Sprinkle with some ripped basil before serving hot or cold with all the delicious juices.
