Briam (Greek Mixed Vegetables in Tomato Sauce)

Step 1
Preheat oven to 350 degrees F (175 degrees C). Place three of the tomatoes, the 1/2 cup olive oil, red wine vinegar, sugar, parsley, mint, basil, oregano, capers, and garlic in the bowl of a food processor and process to create a fresh tomato sauce. Season with salt and black pepper; set aside. Chop the remaining tomato; set aside.

Step 2
Heat the 2 tablespoons olive oil in a skillet over medium heat, and cook and stir the onions until slightly golden, about 10 minutes.

Step 3
Stir together the onions, potatoes, eggplant, zucchini, bell peppers, okra, the reserved chopped tomato, and the fresh tomato sauce, and place the mixture in a large baking pan. If needed, stir in a little water so that the vegetables are just covered with sauce.

Step 4
Bake in the preheated oven until all vegetables are tender, about 1 hour.
