"Made this the other day and it was wonderful a keeper for sure the only change I will make next time is to salute the onions first as they were not quite cooked through in the 20 min of cooking time otherwise wonderful will be making again"

"I left out the red peppers and Swiss cheese. I added provolone. Lived this!"

"I thought about making this recipe, but then I looked at the nutritional information. I do not consider myself that health conscious, but there is no way that I would serve this to anyone that I love (i.e., anyone that I want to live). The recipe contains 25 grams of fat per serving (per 1 and 1/3 cups). I would imagine that most people would ultimately consume about 100 grams of fat per meal, correct? One serving of the meal also contains roughly half the sodium that a person should consume in one day. In light of the fact that a person is not going to just eat one serving, I would imagine that with this one meal, you would ultimately consume twice as much sodium as you're supposed to have in a whole day. I just cannot believe that something so unhealthy can receive so many positive reviews on this website. I love my family way too much to serve them up a heart attack."

"Loved this. I added fresh spinach, since I had a bunch in the frig. My husband and I would definitely like to have this again."
