Preheat the oven to 400°F/200°C
Toss the tomatillos, garlic, jalapeno, poblano, cumin seed, and onion into a roasting dish. Sprinkle with sea salt, freshly cracked black pepper and a healthy pour of EVOO. Stir with a wooden spoon to coat the ingredients thoroughly.
Roast until all of the vegetables are soft approximately 15-20 minutes.
Allow to cool for a few minutes and then add the roasted ingredients, cilantro, lime zest and juice to the food processor.
Blitz on high for 20 seconds or pulse until desired consistency.
Transfer the Roasted Salsa Verde to a bowl and serve warm, at room temperature, or slightly chilled.
