In a saucepan, heat olive oil and brown the meat until all the liquids evaporate, and the meat gets a nice color with some browning at the bottom of the pan. Remove it to a bowl.
Add the carrots, onions, and celery to the pan, and continue sautéing for a few minutes.
Return the meat to the pan. Add white wine and mix until the liquids evaporate, then add tomato paste, crushed tomatoes, water, salt, and pepper. Mix everything well together.
Add the thyme, sage, and bay leaves. Close the pan and cook on low-medium heat for about two hours, stirring occasionally to prevent the sauce from sticking to the bottom.
After two hours, the sauce will have reduced and obtained an amazing texture.
