2 or 3 waxy potatoes, about 1/2 pound, scrubbed and cut into chunks
2 medium zucchini, about 1/2 pound, washed and cut into chunks
1 small onion, peeled and sliced
Olive oil, the best you can lay your hands on
Salt and black pepper
Instructions
Bring a pot of water to a boil and salt it. Meanwhile, prepare the potato and add it to the water. Simmer until the potato is half-cooked, about 10 minutes. (A thin-bladed knife will penetrate the potato easily but not pass through it.)
Add the zucchini and continue to cook. When the potato and zucchini are nearly tender, add the onion. Cook until all three vegetables are tender, then drain, put in a bowl, douse with olive oil and pepper, and mash a little bit. Taste for salt and serve.
