You can make this twist on a traditional gratin with vegetables of your choice. Use courgettes, broccoli, tomatoes or whatever you like. Make sure to dice the vegetables to a similar size.
Made as written except that I left out the tomatoes for hubbys sake. This turned out really good. I cut my potatoes too small which resulted in them not holding their shape but the flavor was still there. With all of the cheese in this dish I was expecting a little more ooey gooey madness but it was still good. The best part about this recipe is that it is easily adaptable to whatever you have on hand. Definitely a keeper! - 24 Feb 2018 (Review from Allrecipes US | Canada)
