Put olive oil in a roaster or oven proof dish, and heat on top of the stove. When the oil is warm add the onion, carrot and celery, sauté for 5 minutes, add the turmeric stir one minute. Add your herbs and stir 1 minute. Add your tomatoes(I put mine through the blender cause I like a smooth sauce). Bring to a gentle boil, turn down heat and add the tomatoe paste. Add salt and pepper and a pinch of white sugar.. Let simmer about 1/2 hour uncovered. Add your beef, put it in the oven covered at 325 degrees for 2 and 1/2- 3 hours. Uncover the 15-20 minutes to let any water evaporate. Your meat will be nice and tender and you will also have a very good pasta sauce.
