In a heavy pot over medium heat, add a tablespoon or so of olive oil . Add onions, carrots, and garlic and stir to start cooking. After a minute or two, pour in the wine, broth, and any juices from seared short ribs. Stir to combine. Set the short ribs back in the pot, put on the lid, and place in the oven for 2 1/2 to 3 hours, or until short ribs are tender and literally falling off the bone.
