This is one that you absolutely need a grill basket for but I don’t think it’s necessary to do anything to them before you toss them on the grill

Approximate quantities: 1 pint of cherry tomatoes; 1 tablespoon olive oil; salt and pepper

Grill at a at a medium high-heat in a grill basket for about 6 minutes, turning, or gently shaking the basket so that they can roll, about halfway through

After about 6 minutes, they’ll begin to char and blister, take them off and then drizzle them with olive oil, salt, and pepper
