Picture skewers sizzling over hot grates: sweet shrimp blush bright pink while a chipotle-lime glaze bubbles into a glossy coat, slipping between charred edges of zucchini.
Mix the glaze: In a bowl, whisk olive oil, lime juice + zest, chipotle powder, paprika, garlic, salt, and pepper until emulsified.
Thread the skewers: Alternate shrimp and zucchini on soaked skewers, curving each shrimp into a gentle “C.” Pat dry, then brush all sides generously with half the glaze.
Preheat the grill: Gas/charcoal grill high direct heat, 500°F+.
Flash-grill: Lay skewers over direct heat, lid open. Grill 2 min; flip and brush with remaining glaze. Cook 2–3 min more until shrimp are opaque and lightly charred.
Rest & serve: Slide skewers to a platter, squeeze extra lime over top, and shower with cilantro if desired.
