I was given this recipe by my older sister a few years back, it was a simple onion, tomato and capsicum peppers pie. She had suggested that I could add mushrooms as my husband likes them so I did. I tend to use the savoury filling that I make for pancake filling and wraps, which is the same as the original recipe I was given. It is a good dish to enjoy as a light lunch with friends or you can make a meal out of it and perhaps serve it with side salad, roast potatoes, stuffed mushrooms etc. It is a good combination of the ingredients and is a very indulgent creamy/cheesy recipe.
