Place all your peppers on a baking tray and bake and roast in a hot oven for 30 min flipping them over halfway through.
Take the peppers out of the oven and leave to cool down before handling. Once the peppers are cool enough, peel off the skins and clean out any seeds (there will be a lot of water inside of each pepper so be careful and drain the water well). Once the peppers are clean chop them all into small cubes and place in a sieve over a bowl, that will drain all the excess water out.
Meanwhile, chop cherry tomatoes into quarters and place in a bowl, add chopped peppers, olive oil, lemon juice and season with salt to taste. Mix all together and enjoy.
