  • 1 (28 ounce) can diced tomatoes, undrained

  • 2 zucchini, scrubbed and cut into 1/2-inch cubes

  • 2 yellow squash, scrubbed and cut into 1/2-inch cubes

  • 1 eggplant, scrubbed and cut into 1/2-inch cubes

  • 1 onion, finely diced

  • 1 teaspoon salt, or to taste

  • ½ teaspoon Italian seasoning, or to taste

  • 1 pinch garlic powder, or to taste

  • 1 pinch ground black pepper, or to taste

  • 1 teaspoon tomato paste (Optional)

  • 2 tablespoons extra-virgin olive oil


  1. Pour diced tomatoes into a large saucepan or Dutch oven over medium-low heat; add zucchini, yellow squash, eggplant, and onion; stir once. Sprinkle salt over vegetables. Bring mixture to a boil and simmer until the vegetables start to cook down, 10 to 15 minutes; stir in Italian seasoning, garlic powder, and black pepper to taste.

  2. Cook uncovered over medium-high heat until the sauce has reduced and vegetables are tender, about 1 hour, stirring often. (Or if preferred, cover pan and cook over low heat 2 to 3 hours.) Stir in tomato paste and adjust seasonings. Drizzle with olive oil just before serving.

Cook's Notes:

Alternate cooking methods: Layer the tomatoes and all the vegetables and seasonings in a deep baking dish or Dutch oven. Cover and bake at 275 degrees F (135 degrees C) for about 3 hours. Towards the end, stir in tomato paste and adjust seasoning, then uncover and return to the oven until liquid reduces as much as desired.

Do the same thing, but in a slow cooker, either on high for 3 to 4 hours or on low for 6 to 8 (or all day). Again, add the tomato paste and uncover to reduce the liquid.
