Before starting, preheat the broiler to high.Wash and dry all produce. Core, then cut pepper into 1/2-inch pieces. Peel, then cut sweet potatoes into 1/2-inch pieces. Peel, then cut onion into 1/2-inch pieces. Roughly chop cilantro.Drain beans.

Heat a large pot over medium-high heat. When hot, add 1 tbsp (2 tbsp) oil, then onions. Cook, stirring occasionally, until slightly softened, 2-3 min. Add chili-garlic sauce and Indian Spice Mix. Cook, stirring constantly, until fragrant, 30 sec.

Meanwhile, add soy sauce, peanut butter, stock powder and 1 cup (2 cups) hot water to a medium bowl. Whisk until smooth.

Add beans, sweet potatoes, peppers, soup base and 1 cup (1 1/2 cups) water to the pot with onions. Bring to a boil over high. Once boiling, reduce heat to medium. Season with salt and pepper. Cover and cook, stirring occasionally, until veggies are tender, 10-12 min. Season with salt and pepper, to taste.

Meanwhile, arrange flatbreads on an unlined baking sheet. Brush tops with 1 tbsp (2 tbsp) oil. Season with salt, then sprinkle with sesame seeds. Gently press down on sesame seeds to adhere. Broil in the middle of the oven until sesame seeds are golden-brown, 3-5 min. (TIP: Keep an eye on them so they don't burn!)

Quarter flatbreads. Divide soup between bowls. Sprinkle cilantro over top. Serve flatbreads alongside for dipping.
