For a richer flavor, brown the veal cubes in a skillet with a little olive oil before adding them to the slow cooker. This step adds depth and complexity to the final dish. If you don't have Swiss cheese on hand, Gruyere or Emmental cheese are excellent substitutes. To prevent the egg noodles from becoming soggy, cook them just before serving. A splash of dry white wine added along with the chicken stock can enhance the sauce's flavor profile.
