I had a similar dish at a friend's aunt's house one time. It was incredible. I've tried to duplicate it and this is pretty close. You can vary your amounts, especially if you aren't a big onion fan. I use just enough oils to coat the pan and keep the veggies from sticking at first. Then I start to add the broth for a little flavor and to help keep it from sticking. You probably won't need to use all the broth that is suggested.
