Richly flavored pesto is the flavor star of this simple fish dish. Earthy walnuts play against vibrant cilantro and tangy lime for a well-rounded experience for your palate that will work well with any firm white fish. Use this as an excuse to try new local fish offered fresh from your fish market.
Tip: When working with hot peppers, wear gloves to protect your skin. Most of the heat is concentrated in the seeds and ribs, so removed these thoroughly to moderate the heat of the pepper.
