Heat the oven to 200°C/400°F. Place the tomatoes, artichokes, olive oil, chilli flakes, oregano, a squeeze of lemon juice and a few slices of lemon in a small baking dish. Place in the oven for 10-15 minutes.
Take the vegetables out of the oven and add the block of feta on top of the vegetables. Switch the oven to a medium high grill/broiler setting. Place the baking dish under the the grill and cook for about 10 minutes keeping a close eye on it to make sure the feta doesn't burn.
Serve the baked feta with a sprinkling of fresh parsley and some crusty bread.
