Combine lime juice, olive oil, cumin,
garlic, syrup, and hot sauce in a small bowl, stirring with a whisk.
Place the shrimp in a shallow bowl. Drizzle 1 tablespoon of the lime
juice mixture over shrimp, tossing gently to coat. Reserve the remaining
lime juice mixture; set aside. Thread shrimp onto metal skewers.
Lightly coat corn with cooking spray. Place shrimp kebabs and corn on a
grill rack coated with cooking spray. Grill 8 minutes, turning kebabs
once and turning corn frequently until browned. Remove from grill; cool
slightly.
Step 3
Remove shrimp from skewers, and place in
a large bowl. Cut kernels from ears of corn. Add corn, chopped lettuce,
green onions, cilantro, black beans, and plum tomatoes to shrimp.
Drizzle reserved lime juice mixture over the shrimp mixture, and toss
gently to combine.
Step 4
Divide tortilla chips evenly among 6
shallow bowls; top each serving with 1 cup shrimp mixture. Combine sour
cream and diced avocado in a small bowl; mash with a fork until well
blended. Top each serving with about 1 tablespoon sour cream mixture.
Serve with a lime wedge, if desired.
