How to Make It
Soak 8 small wooden skewers in water for at least 10 minutes. Meanwhile, in a medium bowl, combine the beans, scallions, lime juice, 2 tablespoons of the oil, and ¼ teaspoon each salt and black pepper.
Heat broiler. Thread the shrimp and pineapple onto the skewers and place on a foil-lined large broilerproof baking sheet. Rub with the remaining 2 tablespoons of oil and season with the cumin, cayenne, ½ teaspoon salt, and ¼ teaspoon black pepper.
Broil the skewers until the shrimp are opaque throughout, 3 to 4 minutes per side. Serve with the tortillas, avocado, salsa verde, cilantro, and hot sauce and the bean salad.
