Preheat your oven to 400°F (200°C).
In a small bowl, combine olive oil, chopped fresh rosemary, thyme, salt, and pepper.
Rub the herb mixture evenly over the pork tenderloin.
Place the pork tenderloin on a baking sheet and roast in the preheated oven for 20-25 minutes, or until the internal temperature reaches 145°F. Allow it to rest before slicing.
While the pork roasts, wash and trim the asparagus. Toss with a small drizzle of olive oil, a pinch of salt, and pepper.
Spread the asparagus on a separate baking sheet and roast in the oven for 10-12 minutes until tender and slightly charred.
Prepare the brown rice according to package instructions, or use a rice cooker until it achieves a light, fluffy texture.
Plate a portion of brown rice, add slices of pork tenderloin, and arrange the roasted asparagus on the side. Enjoy your balanced, nutrient-packed meal!
