Preheat your oven to 400°F (200°C).
Slice the tempeh into 1/4-inch thick pieces. In a shallow dish, toss the tempeh with olive oil, chopped garlic (reserve one clove for broccoli), rosemary, thyme, salt, and pepper.
Allow the tempeh to marinate for at least 15 minutes.
While marinating, rinse and cut the broccoli into florets. Toss the broccoli with the reserved minced garlic, a pinch of salt, and pepper.
Spread the marinated tempeh on a baking sheet lined with parchment paper and roast in the preheated oven for 20-25 minutes, flipping once halfway, until golden and slightly crispy.
Steam or roast the broccoli until just tender, about 8-10 minutes.
Meanwhile, prepare quinoa according to package instructions, typically simmering for about 15 minutes until water is absorbed.
Plate the dish by serving a portion of quinoa topped with herb-roasted tempeh and a side of garlic broccoli. Enjoy your whole food plant-based dinner!
