Once the vegetables are done, remove them from the smoker and allow them to cool slightly.
Peel the charred skin off the tomatoes and garlic cloves.
In a blender or food processor, combine the roasted tomatoes, red onion, red bell pepper, peeled garlic, chipotle peppers, lime juice, cumin powder, salt, and pepper.
Pulse the mixture until you achieve your desired salsa consistency.
By pulsing your blender, you can avoid it turning more frothy. If it turns frothy, its no big deal.
