My mother made hamburger hash: hamburger, onion, and cold cooked potatoes fried together and served with ketchup. Yum.
I've made all kinds of hash since then, but we really liked this one--chicken hash with garlic, red onion, parsnips, and potatoes. With ketchup. I served it with a spinach salad and Rainier cherries.
We ate this at Kluane Lake in the Yukon, where you have camped with us.
