Preheat your oven to 400F and prep the vegetables by chopping the tomatoes and slicing the red peppers.
Then, roast the vegetables. Take the chopped Roma tomatoes, cherry tomatoes, and sliced red peppers and add them to a greased baking tray. Toss with the avocado oil, Italian seasoning, garlic powder, salt, and pepper until evenly coated. Then, add a lemon that is sliced in half to the baking tray so that it is face-up.
Roast the vegetables for 40 minutes until cooked and beginning to caramelize. Remove from the oven and let cool. While the vegetables are cooling, make your quinoa by adding ½ cup quinoa and 1 cup of your vegetable broth to a large pot. Bring to a simmer and cook for 15-20 minutes until the quinoa is cooked through and fluffy.
Once the quinoa is cooked and the vegetables are slightly cooled, add the roasted tomatoes and red peppers to a pot with the canned coconut milk, the additional 1 cup of vegetable broth, tomato paste, and the juice from the roasted lemon.
Use an immersion blender to blend the soup ingredients for 3-5 minutes until completely mixed and the quinoa is broken down. (you can also do this in a standing mixer if you do not have an immersion blender).
Once blended, bring the soup to a boil, stir, and then turn down the heat to a simmer. Simmer the soup for an additional 5 minutes until it is nice and hot.
Remove from stove, ladle into four bowls, and add any desired toppings. For an extra tasty soup, I recommend adding chopped chives, fresh basil, and toasted pine nuts to the top of your soup. Enjoy!
