I printed and tried this recipe from the home page you posted, I made it exactly as written. It was delicious! The onions are NOT optional, they needed to be there. It is not oniony at all because they are cooked slowly with the potatoes. I put some Gouda cheese in but it really didn't need to be there. It made enough for six servings or 4 hungry people. I would serve it with some fresh fruit or sliced tomatoes. My husband didn't like it but he is a VERY picky eater and doesn't like potatoes. He said it was "greasy". DUH! Be sure to make this, it will become a staple in your cooking repertoire. I used white rose potatoes because that's what I happened to have.I used part canola oil and part olive oil, I think you could use all canola oil and it would be ok.
