First, drop peeled and cut potatoes into lightly salted boiling water. Leave them for 8 minutes and then add in the pasta, broken into two-inch pieces. Put a lid on the pot, leaving it slightly ajar, and boil for 8 more minutes. Add the zucchini and let it go another 4 minutes (uncovered) before removing the pot from the heat.
Drain the pasta and veggies but reserve some of the cooking water. This is added back in, along with olive oil and black pepper, and mixed thoroughly. Top with parmesan and serve!
This is simple and rustic, and I could imagine eating it with a hearty bread on a cold day. It's also so easy to make that you could just throw it together in a half hour with whatever veggies are available in your fridge.
