Preheat the grill over medium to medium high heat for 5-10 minutes until hot.
Prepare the peppers by slicing them in half then removing the stems, seeds and pith. Brush both sides of the bell peppers with a little olive oil.
Place the peppers cut side down on the grill. Grill undisturbed with the lid closed on medium heat for 4-5 minutes. Flip to the other side and grill with the lid closed for an additional 4-5 minutes.
Transfer to a pan or plate and sprinkle both sides with sea salt and freshly ground pepper. Serve drizzled with aged balsamic or chimicurri if desired. Enjoy!
