Set an oven rack about 6 inches from the heat source and preheat the oven's broiler.
Place corn, sliced tomato, jalapeno pepper, garlic, and olive oil in a large bowl and toss to lightly coat. Spread oiled ingredients on a baking sheet.
Broil in the preheated oven until vegetables begin to char, about 5 minutes. Remove from the oven and let cool slightly, about 5 minutes.
Transfer charred ingredients to a food processor and add black beans, fire-roasted tomatoes, chili powder, cumin, salt, and lime juice; blend to desired consistency.
