Ingredients

2 Tbsp. olive oil
2 c. or 1 (16 oz.) can plum tomatoes

Heat olive oil in a non-reactive medium saucepan over medium heat.
Add the onion and saute until translucent (5 minutes).
Add tomatoes, crushing against the side of the pan, and cook until water evaporates and tomatoes thicken, about 15 minutes.
Add zucchini, potato and enough water to cover the mixture by about 2-inches.
Bring to a boil.
Reduce the heat to a simmer; season with salt and pepper.
Continue cooking until vegetables are tender, about 20 minutes.
