1 cup bell pepper, mixed colors preferable, chopped
1 tbsp olive oil
1 cup sour cream
1 tbsp adobo sauce
1 avocado, diced
refried beans (optional)
Make the marinade: Combine the garlic, 1/4 cup olive oil, lime juice, cilantro and red pepper flakes in a bowl.
Add the pork tenderloin and the marinade to a large plastic bag. Gently turn the bag to get the pork well coated with the marinade. Place the marinade in the refrigerator to marinade for 1 to 4 hours depending on how much time you have.
Start the cooking by preheating a grill to medium high.
Place the pork tenderloin on the grill.
Grill the pork for 8 minutes on one side, the flip to grill on the other side. Check for doneness after 15 minutes. The pork should take 15 to 20 minutes to be cooked properly. When the pork is done, remove from grill to rest on a platter.
Toss the onion and peppers with 1 tablespoon olive oil, then spread the onion mixture into a grill pan or basket. Place on the grill around the same time you start the pork. Stir occasionally. When the onions have begun to brown and soften after 10 to 15 minutes, remove from grill. Scrape the onion mixture into a serving bowl.
As the pork and onions cook on the grill, combine the sour cream with adobo sauce.
Slice the pork, and put on a platter to serve.
