Preheat the oven to 400°F (200°C) for roasting vegetables and tofu.
Press the tofu to remove excess moisture, then cut it into 1-inch cubes. Toss with a drizzle of olive oil, a pinch of salt, and pepper.
Spread the tofu cubes on a baking sheet and roast for 20-25 minutes until golden and slightly crispy, flipping halfway through.
Meanwhile, chop the broccoli, red bell pepper, and zucchini into even pieces. Toss them with a little olive oil, minced garlic, salt, and pepper, then spread on another baking sheet and roast for 20 minutes until tender and lightly charred.
In a bowl, combine the cooked green lentils, roasted tofu, and vegetables.
Prepare the creamy herb dressing by stirring together the Greek yogurt, fresh lemon juice, chopped parsley, dill, and a little extra minced garlic if desired. Adjust salt and pepper to taste.
Drizzle the lemon-herb yogurt dressing over the lentil and roasted vegetable mixture.
Toss gently to combine all flavors and serve immediately, enjoying the balance of tangy, creamy, and hearty elements.
