Instructions

  1. Step 1: In a medium bowl, whisk together 1/4 cup freshly squeezed orange juice, 2 tbsp freshly squeezed lemon juice, 3 minced garlic cloves, 3 tbsp olive oil, 1 tbsp fresh thyme leaves, 1 tsp sea salt, and 1/2 tsp freshly ground black pepper to create the marinade.
  2. Step 2: Place 1.5 lbs pork tenderloin in a large resealable plastic bag and pour the marinade over it. Seal and refrigerate for at least 1 hour, preferably 3 hours, turning occasionally.
  3. Step 3: Preheat grill to medium-high heat (about 400°F). Remove pork from marinade and discard marinade. Grill pork tenderloin for 15-18 minutes, turning every 5 minutes, until internal temperature reaches 145°F. Remove and let rest for 5 minutes before slicing.
  4. Step 4: Meanwhile, preheat oven to 425°F. Toss 1 lb halved Brussels sprouts with 1 tbsp olive oil and 1/2 tsp sea salt. Spread on a baking sheet and roast for 20-25 minutes, tossing halfway through, until edges are crispy and sprouts are tender.
  5. Step 5: Serve sliced pork tenderloin alongside the roasted Brussels sprouts for a vibrant, Whole30-friendly meal.
