Ingredients

Instructions

  1. Step 1: In a bowl, whisk together 1/4 cup fresh orange juice, 2 tablespoons fresh lemon juice, 3 tablespoons olive oil, 3 minced garlic cloves, 1 tablespoon chopped fresh rosemary, 1 teaspoon sea salt, and 1/2 teaspoon black pepper to make the marinade.
  2. Step 2: Place 1.5 pounds pork tenderloin in a large resealable bag or shallow dish and pour the marinade over it; seal or cover and refrigerate for at least 1 hour or up to 4 hours.
  3. Step 3: Preheat grill to medium-high heat (about 400°F). Remove pork from marinade, letting excess drip off, and grill for 15-18 minutes total, turning every 5 minutes, until internal temperature reaches 145°F.
  4. Step 4: Meanwhile, preheat oven to 425°F. Toss 1 pound trimmed asparagus with 1 tablespoon olive oil and a pinch of sea salt and black pepper; spread on a baking sheet and roast for 10-12 minutes until tender and slightly browned.
  5. Step 5: Let pork rest for 5 minutes before slicing into medallions. Serve alongside the roasted asparagus.
