Preheat your oven to 400°F (200°C).
On a baking sheet, toss the broccoli florets, red bell pepper slices, and zucchini with olive oil, garlic powder, salt, and pepper. Arrange them in a single layer.
Roast the vegetables in the preheated oven for about 15-20 minutes until tender and slightly charred.
While the vegetables are roasting, prepare the crispy chickpeas by rinsing and draining if using canned chickpeas. Pat them dry, season with a pinch of garlic powder, salt, and pepper, and lightly roast in the oven for the last 10 minutes alongside the vegetables, or sauté them in a non-stick pan over medium heat until crisp.
Lightly warm the shelled edamame in a small pan or microwave for about 1-2 minutes.
In a small bowl, combine tahini, lemon juice, a splash of water (to reach desired consistency), and a pinch of salt. Whisk until smooth to create the creamy dressing.
Assemble your Buddha bowl by layering baby spinach at the base. Top with the roasted vegetables, crispy chickpeas, and edamame.
Drizzle the lemon-tahini dressing over the bowl and toss gently to combine all the flavors.
Serve immediately and enjoy your nutrient-packed, flavorful meal.
