While the star of this dish is, of course, the grilled shrimp, but let’s not overlook the grilled limes. “What?” you ask. Grilling adds a subtle, smoky flavor to just about everything, limes included, and makes the fruit extra-juicy. Finishing these tacos with just a squeeze is what takes them over the top. This recipe calls for a jar of green tomatillo salsa, but if you have 10 minutes, try our Fresh tomatillo salsa recipe.
