Recipe kindly shared by the Tesco Community Cookery School with Jamie Oliver. The recipe has been written to be flexible and scalable up to 50 portions. Note: all veg weights are for trimmed, prepped vegetables. Peel (or trim) the alliums, then roughly chop. Peel and slice the garlic. Roughly chop the Mediterranean veg. Place a large pan big enough to hold all the ingredients on a medium heat with the olive oil. Add the mince, alliums and garlic. Cook for 15 to 20 minutes or until the meat juices have evaporated and the veg is golden and softened, stirring frequently. Add the chopped Mediterranean veg and the herbs, and cook for 15 minutes more, or until the vegetables are golden and softened, stirring occasionally. Use a potato masher to gently crush the veg, breaking down any bigger lumps. Add the tomato base sauce, and bring to the boil – remember to note the liquid level in the pan. Add 200ml of water and stock cube (if using) and give everything a good stir. Bring to the boil, then lower the heat and simmer for 40 minutes, or until reduced – the liquid should return to the same level as in step 8. Season to taste with sea salt and black pepper. Delicious served with pasta, in a jacket potato, or use as the base for a cottage pie or lasagne.
