I used 4 potatoes diced, 1 onion diced, 5 hotdogs (I think Clara used 4 but I splurged and actually think 4 would have been right) and oil for frying. Clara uses a couple tablespoons of "sauce" that looked like spagetti sauce perhaps. I didn't have any so just skipped it and added kosher salt and fresh ground peppers.
I really think kids would like this recipe also. Let me know if you give it a try. Oh, and remember to be patient as you cook and brown the potatoes and onions. It takes a while.
