Instructions

  1. Step 1: In a bowl, combine 3 tbsp olive oil, 1/4 cup chopped fresh parsley, 1 tbsp chopped fresh rosemary, 1 tbsp chopped fresh thyme, 3 minced garlic cloves, 1 tsp salt, and 1/2 tsp black pepper to create a marinade.
  2. Step 2: Place 1.5 lbs pork tenderloin in a large resealable bag or shallow dish and pour the marinade over it. Marinate in the refrigerator for at least 1 hour, preferably 3-4 hours.
  3. Step 3: Preheat grill to medium-high heat (about 400°F). Remove pork from marinade and place on the grill. Cook for 15-18 minutes total, turning every 5 minutes, until internal temperature reaches 145°F.
  4. Step 4: While pork grills, toss 1 lb trimmed asparagus spears with 1 tbsp olive oil and a pinch of salt and pepper. Grill asparagus for 5-6 minutes, turning occasionally until tender and slightly charred.
  5. Step 5: Let pork rest for 5 minutes before slicing. Serve slices alongside grilled asparagus.
