Remove meat from pot and add the onions and a pinch of salt and sweat until they begin to soften and become translucent, approximately 7-8 minutes. Do not drain the vegetables. Add the stew meat along with the vegetables and broth. Bring to a simmer, cover and cook for approximately 25-30 minutes. Check stew meat to make sure it is tender and remove from heat.
