  2. Remove the garlic from the roasting tin and squeeze out the softened cloves all over the veg, stirring to evenly distribute. In a medium pan, simmer the chopped tomatoes until bubbling, season well and stir through the roasted veg in the tin. Scatter over the parsley and serve.

Mouthwatering! My version: 3 teaspoons crushed garlic instead of whole. Seasoned with salt, oreganum, ginger, and lemon pepper. Added mushrooms like @lozgreen, balsamic like @Frantic and calamata olives like @catie74 Topped with grated extra matured cheddar and served with flame grilled pork chops and red wine :)

Great recipe, I sliced the potatoes the second time I made it as they took much longer to cook than the rest of the ingredients. Also added some mushrooms the second time, about 20 minutes before serving.

Really fresh tasting casserole with a good texture. I poured the tin of tomatoes into a small ovenproof dish adding a splash of balsamic vinegar and cooked them for the last 20 minutes in the oven with the vegetables. They thickened up well. Served with some chickpea and herb couscous and sausages.

Added some black olives and served with a block of parmesan for people to grate if they wanted it. Good basic family meal

This really felt like it was lacking something. I added a little sugar and vinegar to the tomato sauce but even so it was just a bit dull as a meal. I think perhaps some dry fried chorizo or maybe some kind of cheese if you want to keep it veggie might help this along a bit. I also waited 20mins before I added the tomatoes otherwise they would have been well and truly overdone by the time the potatoes were cooked.

Simmer the chopped tomatoes for 30-45 minutes before adding. It'll get some depth and won't be so watery. Also adding some herbs won't hurt.
