Pre-heat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Dice the red bell pepper, zucchini, and red onion into uniform bite-sized pieces.
Spread the vegetables on the baking sheet, drizzle with olive oil, sprinkle with sea salt and black pepper, and roast for 20 minutes until tender and slightly charred.
While the vegetables roast, place the dry soy granulate in a heat-proof bowl and pour the hot vegetable broth over it.
Let the soy granulate soak for 10 minutes until rehydrated, then drain any excess liquid and squeeze gently with a spoon.
Heat a large non-stick skillet over medium-high heat and add the rehydrated soy granulate.
Season the granulate with garlic powder, smoked paprika, and tamari, then sauté for 8-10 minutes, stirring frequently until browned and crispy.
Remove the roasted vegetables from the oven and add them directly into the skillet with the soy granulate.
Drizzle the toasted sesame oil over the mixture, toss everything together for one minute to combine the flavors, and serve immediately.
