Preheat oven to 350 degrees F (176 C) and arrange red peppers, still whole with stems, on one end of a clean baking sheet. On the other end, arrange almonds and garlic (still in skin).Place baking sheet in oven and roast almonds for 10-12 minutes or until slightly cracked and golden brown. Then remove almonds from pan and set aside. Continue baking garlic for another 5-8 minutes. Then remove and set aside.With peppers still on baking sheet, increase heat to 475 degrees F (246 C). Allow red peppers to roast until skin is bubbled and mostly blackened, turning/flipping halfway through to char both sides (~10 minutes).Once they're properly charred, wrap roasted red peppers in foil and steam for 2-3 minutes. Then peel away skin, seeds, and core. Also remove skin from roasted garlic.Add peeled peppers, almonds, garlic, diced tomatoes, vinegar, paprika, sea salt, pepper, maple syrup or coconut sugar, and (optional) harissa or pepper flake to a high-speed blender. Purée until smooth, scraping down sides as needed. Taste and adjust seasonings as desired, adding more harissa or pepper flake for heat, salt for saltiness, vinegar for acidity, maple syrup or coconut sugar for sweetness, or paprika for smokiness.Add the soup to a large pot and add the vegetable broth and smashed chickpeas. Bring to a simmer over medium heat. Then reduce heat to low and continue simmering for 10-15 minutes, stirring occasionally.Serve as is or with a bit of pine nuts, fresh herbs, vegan parmesan cheese, or your favorite bread or roll.Leftovers keep well covered in the refrigerator for 3-4 days, though best when fresh.
