Preheat your oven to 425°F (220°C).
Cut the broccoli into bite-size florets and slice the tempeh into cubes or strips.
In a bowl, toss the tempeh with half of the olive oil, a pinch of salt, and pepper. Allow it to marinate for 5 minutes.
On a baking sheet, spread the broccoli florets. Drizzle with the remaining olive oil, and season with salt and pepper.
Roast the broccoli in the preheated oven for 20 minutes, stirring halfway through, until the edges are crispy.
While the broccoli roasts, heat a pan over medium heat and sauté the marinated tempeh until golden brown on all sides, about 5-7 minutes.
In a small bowl, whisk together the lemon juice, minced garlic, and a dash of salt and pepper.
Once cooked, combine the roasted broccoli and sautéed tempeh in a serving bowl. Drizzle the lemon garlic dressing over the top and toss gently to coat.
Serve warm and enjoy your flavorful, protein-packed dish.
