In this irresistible snack, charred poblano pepper and pureed cilantro and serrano chiles serve as a built-in salsa, layering spicy, garlicky flavors into the rich, melted cheese. Flaming it with tequila makes the whole thing a little extra. The pickled carrots on top add acidity and brightness; feel free to substitute pickled jalapeno slices if you have some on-hand.
