• Pinch cayenne pepper (or more if you're brave!)
• 1 cup freshly squeezed grapefruit juice
• 2 limes, juiced
• 2 tablespoons extra-virgin olive oil
• 2 pounds jumbo shrimp, peeled and deveined, tails left intact
• 2 large ripe and firm mangos, peeled, sliced, and cut into long wedges
• 4 ears corn, husks and corn silk discarded
• 3 tablespoons extra-virgin olive oil
• Kosher salt and freshly ground black pepper
• 2 ripe Hass avocados, peeled, pitted, and cubed
• 1 lime, juiced
• 1 small red onion, finely chopped
• 1 red bell pepper, seeded and finely chopped
• 1 jalapeno pepper, seeded and finely minced
• 3 tablespoons chopped fresh cilantro or basil, plus more for garnish
• 2 tablespoons red wine vinegar
• 6 cups mixed salad greens or baby spinach

Instructions

1. Put wooden skewers in a pan of water for 30 minutes, so they don't burn on the grill.
2. To make the marinade:
3. Put the garlic on a cutting board and coarsely chop. Sprinkle with coarse salt and mash the garlic into a paste with the side of the knife. Put the garlic paste in a bowl. Add the cumin, oregano, paprika, black pepper, and cayenne. Mix to combine. Stir in the grapefruit juice, lime juice, and oil. Pour out about 1/3 of the marinade and put into a small bowl. Reserve for dressing the salad.
4. Thread the shrimp and mango onto separate skewers and put side-by-side in a baking dish. Pour the remaining marinade over the shrimp and mango; cover with plastic wrap. Put in the refrigerator and allow to marinate for about 30 minutes, flipping the skewers occasionally.
5. To make the salsa:
6. Preheat an outdoor grill or grill pan to medium-high (you may also preheat the oven broiler.)
7. Rub the corn with 2 tablespoons of the oil and season with salt and pepper. Put the corn directly on the grill grates (or put in a baking pan if using oven method) and cook until the kernels are slightly charred on all sides, turning every couple of minutes. Remove from the heat. Using a sharp knife, carefully cut the kernels off of the cobs and put in a mixing bowl. Add the avocado, lime juice, onions, bell peppers, jalapeno, cilantro, vinegar, and remaining 1 tablespoon of oil. Season with salt and pepper.
8. Grill (or broil) the shrimp until curled, pink and slightly charred on both sides, about 2 to 3 minutes total cooking time. Cook the mangos until grill marks appear, about 1 minute on each side.
9. Divide the mixed greens evenly among 4 plates. Drizzle the reserved mango marinade over the greens. Top with shrimp and mango skewers and a couple of spoonfuls of the roasted corn and avocado salsa. Garnish with some chopped cilantro serve with remaining salsa on the side.
