Preheat oven to 400 degrees, and line a baking sheet with foil or parchment paper. Mist with cooking spray.
Cut the eggplants in half lengthwise, and place on baking sheet cut side up. Mist with cooking spray, and sprinkle with salt. Place in oven and roast for about 20-25 minutes, or until the eggplant becomes very soft and tender, and begins to char. Remove from oven and let cool for about 10 minutes.
In the meantime, place all the other diced veggies in a large bowl. Now, scoop out the inside flesh from the eggplant and add it to the bowl. The flesh should be very soft and squishy. Mash it with a fork to help break it apart.
Add in olive oil, cilantro, garlic, lemon juice, and salt and pepper and mix well. Serve warm or cold.
