A sauce made with bright green tomatillos, sweet bell pepper, spicy jalapeno and piquant poblano.
Preheat the oven to 400ºF.
Spread the tomatillos, garlic, jalapenos, bell pepper, poblano and onion on a baking sheet and season with salt and pepper. Drizzle with olive oil and toss everything to coat. Roast until the vegetables are soft, 10 to 15 minutes. Let cool for a few minutes.
Remove the seeds from the peppers. Put all of the roasted vegetables and the cilantro into a food processor or blender. Process until still a bit chunky. Thin with some water if it is too thick. Stir in the lime zest and juice. Let cool completely.
Use immediately or pour into freezer bags, label and freeze.
