Dale's Awesome Sauce

Preheat an outdoor grill for high heat, and lightly oil the grate.

Rub tomato halves, bell pepper halves, onion halves, and garlic halves with olive oil; season with garlic powder, sea salt, and black pepper.

Cook vegetables on preheated grill, turning regularly, until wrinkled and slightly charred, 5 to 10 minutes.
