Cut Tomatoes, Coat & Season: Preheat the oven, then cut your tomatoes in half. Arrange them on a baking sheet. Spray the tomatoes with cooking spray then season with salt and pepper.
Combine Ingredients In Pot: In a large pot or dutch oven, heat some olive oil or vegan butter over medium heat. Add the tomatoes, rice, garlic, veggie broth, and seasoning to the pot.
Blend Soup: Use an immersion blender to puree the soup right in the pot. If you don’t have a stick blender, carefully transfer the hot liquid to a high-speed blender or food processor and puree.
