Slice off the top of the peppers and remove the seeds from the inside.
Slice the peppers into ½" slices. The smaller slices allow for a more even charring.
Toss the peppers with olive oil. This should be an extremely light coat and will help them not stick to the grill grate.
Preheat the grill to about 350℉ on direct heat.
Add the peppers to the grill and let them cook for 7-10 minutes per side. Check them throughout to make sure they do not become too charred.
Remove from the grill and sprinkle with salt and pepper.
Notes
Aim for a light charring. That adds an amazing flavor without overpowering the vegetable. Mix with your favorite herbs and seasonings after removing from the grill.A little oil goes a long ways. Don't add too much.
