Preheat broiler to high.
Arrange tomatillos on a baking sheet. Broil, about 4-inches from the heating element, for about 10-15 minutes, until beginning to char.
Meanwhile, heat oil in a large skillet over medium heat. Add the garlic and chiles and saute for 4-5 minutes, until fragrant and the garlic turns light golden.
Add the tomatillos, chiles, garlic, tomatoes, cumin and salt to a blender or food processor.
Process until smooth.
Season with additional salt, to taste.
Refrigerate for at least 30 minutes and enjoy!
