Pre-heat the oven to 425 degrees.
Divide the eggplant, tomatoes, onion, and garlic between 2 Silpat lined or parchment paper lined baking sheets. Toss the veggies with the olive oil, sea salt, and pepper. Roast the veggies at 425 degrees for 25 minutes.
When the veggies are done roasting, bring 1 quart of bone broth with the oregano and basil to a simmer. Add the roasted veggies and puree the soup until smooth. Taste for sea salt and pepper to your liking.
You can garnish with a dollop of sour cream, or stir in some raw milk or coconut cream if you wish. It is just as creamy and delicious without if you can't have dairy or don't have access to coconut milk. I love the richness the raw milk or sour cream gives - I have also found that a drizzle of olive oil gives that same rich, buttery feel.
