Directions

1. Preheat a grill: If using a charcoal grill, make a fire in your grill. When the charcoals are completely covered in gray ash, hold your hand about 5 inches above the grill grid; count how many seconds you can comfortably leave it there. When you can hold your hand above the grill for 2 to 3 seconds, you have medium-high heat and are ready to grill. If you are using a gas grill, heat the grill for 15 minutes with the lid closed. Before beginning to cook, reduce the temperature by turning the knobs to medium-high.
2. Place bell pepper on grill and grill on all sides until skin is black and blistered, 8 to 12 minutes. Transfer pepper to a paper bag, fold bag closed, and set aside.
3. Place corn on grill and cook on all sides until tender and beginning to brown, 3 to 4 minutes. Transfer corn to a cutting board and remove kernels from cob; you should have about 1 1/2 cups kernels. Transfer corn to a medium bowl and set aside.
4. When pepper is cool enough to handle, gently peel the skin from the pepper. Cut pepper in half lengthwise; remove seeds, ribs, and stem. Chop pepper.
5. Transfer chopped pepper to bowl with corn, along with basil, oil, vinegar, and garlic; toss until well combined. Season with salt and pepper.
