In a saucepan, over medium high heat, combine tomatillos and water to cover and bring to a gentle boil. Cook, uncovered, until soft but not soggy, 8-10 minutes. Drain and transfer to a blender. Almost everyone in the pool: onion, chili peppers, garlic and salt.
Pour into a bowl and garnish with cilantro.
