First, preheat your oven to 425°F and line a baking sheet with parchment paper.

In a medium saucepan, heat up some olive oil over medium heat. Once hot, add the rice and sauté it for 2-3 minutes, stirring regularly. Then, add water and let the rice cook until it's soft and the water has been absorbed. This usually takes around 7 to 10 minutes.

Next, it's time to prepare the veggies. Wash, peel, and cut them into bite-sized pieces and place them on the prepared baking sheet. Drizzle with olive oil, salt, black pepper, and garlic powder. Give everything a good toss to ensure even coating, and then roast for around 30 minutes until the vegetables are tender and golden brown. Once done, set them aside to cool until ready to serve.

While the veggies are cooking, it's time to prepare the chickpeas. Combine them with olive oil, salt, and black pepper, and set them aside.

In a small bowl, whisk together the hummus, lemon juice, olive oil, water, garlic powder, salt, and black pepper to make a delicious dressing.

Now, it's time to put it all together. Layer the lettuce, roasted vegetables, and rice in a large bowl. Add in the seasoned chickpeas and vegan feta. Toss everything together until well combined.
