Place the tomatoes, garlic, onion, jalapeno and poblano onto a baking sheet. Drizzle with the olive oil and season with salt and pepper. Roast until charred in spots, about 15 minutes. Set aside and allow to cool slightly, about 5 minutes.
Transfer the roasted vegetables to a blender. Add the lime zest and juice and puree until smooth, being careful not to fill the blender too full. Transfer to a bowl and stir in the cilantro. Taste and adjust the seasoning if needed. Goes great with chips or alongside enchiladas.
